  • Installing sfJqueryTreeDoctrineManagerPlugin to Symfony 1.4

    - by Christine Q.
    I have faced serious difficulties while installing sfJqueryTreeDoctrineManagerPlugin to Symfony 1.4 w/ Doctrine ORM. The installation directly from the server did not work out like with previous plugins that I have installed: C:\pathsymfony plugin:install sfJqueryTreeDoctrineManagerPlugin plugin installing plugin "sfJqueryTreeDoctrineManagerPlugin" No release available for plugin "sfJqueryTreeDoctrineManagerPlugin" This is why I needed to install the plugin by downloading the tgz-archive and install it manually like this: C:\pathsymfony plugin:install "C:\path\to\downloads\sfJqueryTreeDoctrineManagerPlugin-1.2.4.tgz" plugin installing plugin "C:\path\to\downloads\sfJqueryTreeDoctrineManagerPlugin-1.2.4.tgz" sfSymfonyPluginManager Installing web data for plugin I guess everything should be fine this far? After that I edited \apps\admin\config\settings.yml like instructed in the plugins readme file. all: .settings: enabled_modules: [default, sfJqueryTreeDoctrineManager] I also checked that the plugin was enabled in \config\ProjectConfiguration.class.php like this: $this->enablePlugins(array( // other plugins, 'sfJqueryTreeDoctrineManagerPlugin' )); I published assets and cleared cache: C:\pathsymfony plugin:publish-assets >> plugin Configuring plugin - sfJqueryTreeDoctrineManagerPlugin C:\pathsymfony cc Finally I added the required helper to the newly created apps\admin\modules\category\templates\indexSuccess.php <?php use_helper("sfJqueryTreeDoctrine"); echo get_nested_set_manager("Category", "name"); When loading the page I unfortunately get the following error: 500 | Internal Server Error | InvalidArgumentException Unable to load "sfJqueryTreeDoctrineHelper.php" helper in: SF_ROOT_DIR\apps\admin\modules/businessunitgroup/lib/helper, SF_ROOT_DIR\apps\admin\lib/helper, SF_ROOT_DIR\lib/helper, SF_SYMFONY_LIB_DIR/helper. The file sfJqueryTreeDoctrineHelper.php exists indeed but not in any previously mentioned folder. The file can only be found in the folder \plugins\sfJqueryTreeDoctrineManagerPlugin\lib\helper. I guess that Symfony doesn't look to that folder while finding helpers? I have tried to move the helper file to one of the previously mentioned folders. As expected, that changes the error. Now I get: 500 | Internal Server Error | sfConfigurationException The component does not exist: "sfJqueryTreeDoctrineManager", "manager". Unfortunately I can't figure out how should I be able to retrieve the "missing" component from the correct folder. I would be very grateful for any advice to help me forward. By the way, I am aware that there are other nested-set / tree plugins available for Symfony (like sfDoctrineTreePlugin and caPropelTreePlugin) but unluckily those are either uncompatible or too limited for my needs.

  • Twig templates, inheritances and block usage

    - by user846226
    I've created three templates using Twig. The first one has block A defined in it, the second one extends from the first one, but includes a third template which sets the content of block A. When loading, through the browser, the url which renders b.html.twig, the content in block A (defined by the 3th template) is not positioned block _A is defined. Example: <!-- base.html.twig --> {% block _css '' %} {% block _header '' %} {% block _content '' %} {% block _footer '' %} {% block _js '' %} <!-- layout.html.twig --> <!-- header and footer are placed in the raight zone --> {% extends ::base.html.twig %} {% block _header %} {% render "MyBundleBundle:Header:header" %} {% endblock %} {% block _footer %} {% render "MyBundleBundle:Footer:footer" %} {% endblock %} <!-- my_template.html.twig --> <!-- content is also placed in the right zone but css and js blocks in the included template are not placed where declared in base.html.twig --> {% extends MyBundleBundle::layout.html.twig %} {% block _content %} SOME_CONTENT {% include MyBundleBundle::my_included_template.html.twig %} {% endblock %} <!-- my_included_template.html.twig --> {% block _css %} <link.......................> {% endblock %} {% block _js %} <script..................> {% endblock %} MORE CONTENT BELONGING TO THE INCLUDED TEMPLATE What i expect here is, _css blocks content to appear on top of the page and _js block content at the bottom, but that's not happening. I hope you can see where i'm going wrong, thanks!

  • Jmeter is not extracting correctly the value with the reg ex extractor.

    - by Chris
    Jmeter is not extracting correctly the value with the reg ex. When I play with this reg ex (NAME="token" \s value="([^"]+?)") in reg ex coach with the following html everything work fine but when adding the reg with a reg ex extrator to the request he doesn't found the value even if it's the same html in output. <HTML>< script type="text/javascript" > function dostuff(no, applicationID) { submitAction('APPS_NAME' , 'noSelected=' + no + '&applicationID=' + applicationID); }< /script> <FORM NAME="baseForm" ACTION="" METHOD="POST"> <input type="hidden" NAME="token" value="fc95985af8aa5143a7b1d4fda6759a74" > <div id="loader" align="center"> <div> <strong style="color: #003366;">Loading...</strong> </div> <img src="images/initial-loader.gif" align="top"/> </div> <BODY ONLOAD="dostuff('69489','test');"> From the reg ex extractor reference name: token Regex: (NAME="token" \s value="([^"]+?)") template : $2$ match no.:1 Default value: wrong-token The request following my the POST of the previous code is returning : POST data: token=wrong-token in the next request in the tree viewer. But when I check a the real request in a proxy the token is there. Note : I tried the reg ex without the bracket and doesn't worked either. Do anybody have a idea whats wrong here ? Why jmeter can't find my token with the reg ex extrator ?

  • Embedding Lua functions as member variables in Java

    - by Zarion
    Although the program I'm working on is in Java, answering this from a C perspective is also fine, considering that most of this is either language-agnostic, or happens on the Lua side of things. In the outline I have for the architecture of a game I'm programming, individual types of game objects within a particular class (eg: creatures, items, spells, etc.) are loaded from a data file. Most of their properties are simple data types, but I'd like a few of these members to actually contain simple scripts that define, for example, what an item does when it's used. The scripts will be extremely simple, since all fundamental game actions will be exposed through an API from Java. The Lua is simply responsible for stringing a couple of these basic functions together, and setting arguments. The question is largely about the best way to store a reference to a specific Lua function as a member of a Java class. I understand that if I store the Lua code as a string and call lua_dostring, Lua will compile the code fresh every time it's called. So the function needs to be defined somehow, and a reference to this specific function wrapped in a Java function object. One possibility that I've considered is, during the data loading process, when the loader encounters a script definition in a data file, it extracts this string, decorates the function name using the associated object's unique ID, calls lua_dostring on the string containing a full function definition, and then wraps the generated function name in a Java function object. A function declared in script run with lua_dostring should still be added to the global function table, correct? I'm just wondering if there's a better way of going about this. I admit that my knowledge of Lua at this point is rather superficial and theoretical, so it's possible that I'm overlooking something obvious.

  • S3 Backup Memory Usage in Python

    - by danpalmer
    I currently use WebFaction for my hosting with the basic package that gives us 80MB of RAM. This is more than adequate for our needs at the moment, apart from our backups. We do our own backups to S3 once a day. The backup process is this: dump the database, tar.gz all the files into one backup named with the correct date of the backup, upload to S3 using the python library provided by Amazon. Unfortunately, it appears (although I don't know this for certain) that either my code for reading the file or the S3 code is loading the entire file in to memory. As the file is approximately 320MB (for today's backup) it is using about 320MB just for the backup. This causes WebFaction to quit all our processes meaning the backup doesn't happen and our site goes down. So this is the question: Is there any way to not load the whole file in to memory, or are there any other python S3 libraries that are much better with RAM usage. Ideally it needs to be about 60MB at the most! If this can't be done, how can I split the file and upload separate parts? Thanks for your help. This is the section of code (in my backup script) that caused the processes to be quit: filedata = open(filename, 'rb').read() content_type = mimetypes.guess_type(filename)[0] if not content_type: content_type = 'text/plain' print 'Uploading to S3...' response = connection.put(BUCKET_NAME, 'daily/%s' % filename, S3.S3Object(filedata), {'x-amz-acl': 'public-read', 'Content-Type': content_type})

  • How to setup a Zend_Application with an application.ini and a user.ini

    - by Peter Smit
    I am using Zend_Application and it does not feel right that I am mixing in my application.ini both application and user configuration. What I mean with this is the following. For example, my application needs some library classes in the namespace MyApp_ . So in application.ini I put autoloaderNamespaces[] = "MyApp_". This is pure application configuration, no-one except a programmer would change these. On the other hand I put there a database configuration, something that a SysAdmin would change. My idea is that I would split options between an application.ini and an user.ini, where the options in user.ini take preference (so I can define standard values in application.ini). Is this a good idea? How can I best implement this? The idea's I have are Extending Zend_Application to take multiple config files Making an init function in my Bootstrap loading the user.ini Parsing the config files in my index.php and pass these to Zend_Application (sounds ugly) What shall I do? I would like to have the 'cleanest' solution, which is prepared for the future (newer ZF versions, and other developers working on the same app)

  • Valueurl Binding On Large Arrays Causes Sluggish User Interface

    - by Hooligancat
    I have a large data set (some 3500 objects) that returns from a remote server via HTTP. Currently the data is being presented in an NSCollectionView. One aspect of the data is a path pack to the server for a small image that represents the data (think thumbnail for simplicity). Bindings works fantastically for the data that is already returned, and binding the image via a valueurl binding is easy to do. However, the user interface is very sluggish when scrolling through the data set - which makes me think that the NSCollectionView is retrieving all the image data instead of just the image data used to display the currently viewable images. I was under the impression that Cocoa controls were smart enough to only retrieve data for the information that is actually being output to the user interface through lazy loading. This certainly seems to be the case with NSTableView - but I could be misguided on this thought. Should valueurl binding act lazily and, moreover, should it act lazily in an NSCollectionView? I could create a caching mechanism (in fact I already have such a thing in place for another application - see my post here if you are interested http://stackoverflow.com/questions/1740209/populating-nsimage-with-data-from-an-asynchronous-nsurlconnection) but I really don't want to go this route if I don't have to for this specific implementation as the user could potentially change data sets often and may only want small sub-sets of the data. Any suggested approaches? Thanks!

  • Need events to execute on timer events, metronome precision.

    - by user295734
    I setup a timer to call an event in my application. The problme is the event execution is being skewed by other windows operations. Ex. openning and window, loading a webpage. I need the event to excute exactly on time, every time. When i first set up the app, used a sound file, like a metronome to listen to the even firing, in a steady state, its firing right on, but as soon do something in the windows environment, the sound fires slower, then sort of sppeds up a bit to catch up. So i added a logging method to the event to ctahc the timer ticks. From that data, it appears that the timer is not being affected by the windows app, but my application event calls are being affected. I figured this out by checking the datetime.now in the event, and if i set it to 250 milliseconds, which is 4 clicks per second. You get data something like below. (sec):(ms) 1:000 1:250 1:500 1:750 2:000 2:250 2:500 2:750 3:000 3:250 3:500 3:750 (lets say i execute some windows event)(time will skew) 4:122 4:388 4:600 4:876 (stop doing what i was doing in windows) (going to shorten the data for simplicit, my list was 30sec long) 5:124 5:268 5:500 5:750 (you would se the time go back the same milliseconds it was at the begining) 6:000 6:250 6:500 6:750 7:000 7:250 7:500 7:750 So i'm thinking the timer continues to fire on the same millisecond every time, but its the event that is being skewed to fire off time by other windows operations. Its not a huge skew, but for what i need to accomplish, its unacceptable. Is there anyhting i can do in .NET, hoping to use XAML/WPF application, thats will correct the skewing of events? thx.

  • loaded resources looks ugly

    - by Xaver
    I have the TreeView class using in my project. I use icons for it.First i load icons so: ImageList^ il = gcnew ImageList(); il->Images->Add(Image::FromFile("DISK.ico")); il->Images->Add(Image::FromFile("FILE.ico")); il->Images->Add(Image::FromFile("FOLDER.ico")); treeView1->ImageList = il; All was good. But i dont like that if i delete my icons from directory of project. there is error in my project. I decide to add icons in .resx file. Now icons loading look so: ImageList^ il = gcnew ImageList(); Resources::ResourceManager^ resourceManager = gcnew Resources::ResourceManager ("FilesSaver.Form1", GetType()->Assembly); Object^ disk = resourceManager->GetObject("DISK"); il->Images->Add(reinterpret_cast<Image^>(disk)); Object^ file = resourceManager->GetObject("FILE"); il->Images->Add(reinterpret_cast<Image^>(file)); Object^ folder = resourceManager->GetObject("FOLDER"); il->Images->Add(reinterpret_cast<Image^>(folder)); treeView1->ImageList = il; And why icons in the TreeView looks ugly (they look lighter and have a big black border). Why did this happen?

  • jQuery UI Dialog and Textarea Focus Issue

    - by Gimli
    I'm working on a modal comment system using jQuery and jQuery UI, but I'm having some issues with focus. I have a series of divs inside the modal to switch between Login and Add comment, as below: <div id="modal" title="Loading"> <div id="modalContent"></div> <div id="modalLogin"> <div class="loginBox"></div> <div class="addCommentBox"></div> <div class="commentReview"></div> </div> </div> Inside of the addCommentBox div, I've got the comment code: <form action="/comments/add" class="addCommentForm" name="addCommentForm" method="post"> <textarea name="content" class="addCommentContent"></textarea> <button value="Add Comment" type="submit" class="commentPost"/> <button value="Clear Comment" type="submit" id="clearComment"/> </form> The issue is that about half the time after opening the dialog the textarea inside the addCommentBox div doesn't react to keyboard inputs when selected. The mouse works correctly and will allow text to be selected, but keyboard control does nothing. I have no event listeners on the textarea. I've got some on the buttons, but they are targeting only the buttons. The only thing that happens in the HTML seems to be the fact that every time I click on the modal, the z-index increases for the overall modal div. I have set the addCommentBox div to have a z-index of 9999, greater than the z-index of the modal. Any suggestions or directions to research would be greatly appreciated. Thanks!

  • img onload doesn't work well in IE7

    - by rmeador
    I have an img tag in my webapp that uses the onload handler to resize the image: <img onLoad="SizeImage(this);" src="foo" > This works fine in Firefox 3, but fails in IE7 because the image object being passed to the SizeImage() function has a width and height of 0 for some reason -- maybe IE calls the function before it finishes loading?. In researching this, I have discovered that other people have had this same problem with IE. I have also discovered that this isn't valid HTML 4. This is our doctype, so I don't know if it's valid or not: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Is there a reasonable solution for resizing an image as it is loaded, preferably one that is standards-compliant? The image is being used for the user to upload a photo of themselves, which can be nearly any size, and we want to display it at a maximum of 150x150. If your solution is to resize the image server-side on upload, I know that is the correct solution, but I am forbidden from implementing it :( It must be done client side, and it must be done on display. Thanks. Edit: Due to the structure of our app, it is impractical (bordering on impossible) to run this script in the document's onload. I can only reasonably edit the image tag and the code near it (for instance I could add a <script> right below it). Also, we already have Prototype and EXT JS libraries... management would prefer to not have to add another (some answers have suggested jQuery). If this can be solved using those frameworks, that would be great. Edit 2: Unfortunately, we must support Firefox 3, IE 6 and IE 7. It is desirable to support all Webkit-based browsers as well, but as our site doesn't currently support them, we can tolerate solutions that only work in the Big 3.

  • Rails ajax jquery problem

    - by user283179
    Ok I have this problem I'm trying to use Jquery to load a partial in replace of a listed object. loadshow: $(function() { $(".style_image_<%= style.id %> a").click(function() { $(".style_image_<%= style.id %>").html("loading... ") $(".style_image_<%= style.id %>").html("<%= escape_javascript(render("show")) %>") $.get(this.href, null, null, "html"); return false; }); }); _show.html.erb: <%=link_to image_tag(style.cover.pic.url(:normal)), style %> I'm getting this error: missing ) after argument list [Break on this error] $(".style_image_<%= style.id %>").htm...scape_javascript(render("show")) %>")\n There is two problems with my code here the first is the click function is not targeting the .style_image_<%= style.id % .... i.e (.style_image_42) if I replace the css target with 42 instead of _style.id the click target works; why is this? And with or without this change the _show partial is not render and the above error is given. Not really that good with Javascript any help would be great! P.s. The effect I really want is like one of those super cool cargo themes: http://cargocollective.com/publikspace Thanks Dan!

  • Symfony + JQueryUI Tabs navigation menu question

    - by Andy Poquette
    I'm trying to use the tabs purely as a navigational menu, loading my pages in the tabs, but being able to bookmark said tabs, and have the address bar correspond with the action I'm executing. So here is my simple nav partial: <div id='tabs'> <ul> <li id='home'><a href="<?php echo url_for('post/index') ?>" title="Home">Home</a></li> <li id='test'><a href="<?php echo url_for('post/test') ?>" title="Test">Test</a></li> </ul> </div> And the simple tabs intializer: $(document).ready(function() { $('#tabs').tabs({spinner: '' }); }); My layout just displays $sf_content. I want to display the content for the action I'm executing (currently home or test) in the tab, via ajax, and have the tab be bookmarkable. I've googled this like 4000 times and I can't find an example of what I'm trying to do. If anyone has a resource they know of, I can look it up, or if you can help, I would greatly appreciate it. Thank you in advance.

    I have 50+ textareas that I am using tinyMCE with. Instead of loading each one I am just initialising them, then activing them later on request Initialisation tinyMCE.init({ mode : "none", theme : "advanced", theme_advanced_buttons1 : "", theme_advanced_buttons2 : "", theme_advanced_buttons3 : "", theme_advanced_toolbar_location : false, theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : false, theme_advanced_resizing : true, auto_focus : false }); Edit Observer $('ul span.edit-details').click(function () { var id = this.id; id = id.replace('edit-',''); tinyMCE.execCommand('mceToggleEditor',false,'editor-'+id); }); UPDATE I have also tried $('ul span.edit-details').click(function () { var id = this.id; id = id.replace('edit-',''); if($('#details-'+id).is(":hidden")) { $('#details-'+id).show(); tinyMCE.execCommand('mceAddControl',false,'editor-'+id); } else { $('#details-'+id).hide(); tinyMCE.execCommand('mceRemoveControl',false,'editor-'+id); } }); The problem I have is that when tinyMCE.execCommand('mceToggleEditor',false,'editor-'+id); fires the pages focuses/scrolls to that textarea, even if it is already in the viewport. Any suggestions on how to stop this? Thanks!

  • Scrollbar with Sprite and Rectangle won't move text, just the Rectangle it's painted on.

    - by WebDevHobo
    Warning: school assignment. For those of you still with me, I am tasked with making some scrollable content in Flash. Load in a TextFile using LoadURL(), then display it. To get the text, we've written our own class TextFieldExtended, which is basically just there to give the textfile location to the constructor and then have the class do the various steps of getting it and loading it for you. So I needed to get a Scrollbar, which I got here: http://kirupa.com/forum/showthread.php?t=245468 (all files in a zip linked at the end of this text) The thing is, it works with Sprites. After trying to get it to accept TextFieldExtended, I bumped into a block, since the scrollbar relied heavily on a Sprite property that TextFieldExtended didn't have or could have. So I tried adding the TextFieldExtended instance to a Sprite instance using addchild. A problem occurs here that I do not know how to handle. It seems that a Rectangle is drawn and the Text is drawn on that. I say this because the scrollbar moves the Rectangle up and down a bit, but the text doesn't scroll, just the Rectangle it is positioned in and the text then moves along with it. My question: can this be fixed, or is does this implementation of scrollbars need a lot of adaptations before this is possible? If so, any scrollbars you can recommend, because it's too extended for me at this point. All files: http://www.mediafire.com/?q2ium22gmox This was made in Flash CS4 using ActionScript3. The Example class is the final implementation

  • Web API Getting Http 500 error : Issue Solved See Below

    - by Joe Grasso
    Here is my MVC Controller and everything is fine: private UnitOfWork UOW; public InventoryController() { UOW = new UnitOfWork(); } // GET: /Inventory/ public ActionResult Index() { var products = UOW.ProductRepository.GetAll().ToList(); return View(products); } Same method call in API Controller gives me an Http 500 Error: private UnitOfWork _unitOfWork; public TestController() { _unitOfWork = new UnitOfWork(); } public IEnumerable<Product> Get() { var products = _unitOfWork.ProductRepository.GetAll().ToList(); return products; } Debugging shows that indeed there is data being returned in both controllers' UOW calls. I then added a customer configuration in Global: public static void CustomizeConfig(HttpConfiguration config) { config.Formatters.Remove(config.Formatters.XmlFormatter); var json = config.Formatters.JsonFormatter; json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); } I am still receiving an Http 500 in API Controller ONLY and at a loss as to why. Any ideas? UPDATE: It appears using lazy loading caused the problem. When I set the associated properties to NON-VIRTUAL the Test API provided the necessary JSON string. However, whereas before I had the Vendor class included, I only have VendorId. I really wanted to included the associated classes. Any ideas? I know there are alot of smart people out there. Anyone?

  • Passing youtube video id from video feed to flash

    - by Grant Anderson
    I'm working on a flash web application (Actionscript 2.0) for my honours project but am having trouble embedding youtube videos. Basically the user selects symbols which queries the youtube api with certain tags depending on the symbols chosenand a random video is then picked from the first 30 videos. I have this working using the following code: on (release) { url="http://gdata.youtube.com/feeds/api/videos?q=danger+passion&orderby=published&start-index="+random(30)+"&max-results=1&v=2" getURL(url); } but this just displays a webpage with a link to the youtube video. This is the code I'll be using as the foundations for the player: // create a MovieClip to load the player into var ytplayer:MovieClip = _root.createEmptyMovieClip("ytplayer", 1); // create a listener object for the MovieClipLoader to use var ytPlayerLoaderListener:Object = { onLoadInit: function() { // When the player clip first loads, we start an interval to // check for when the player is ready loadInterval = setInterval(checkPlayerLoaded, 250); } }; var loadInterval:Number; function checkPlayerLoaded():Void { // once the player is ready, we can subscribe to events, or in the case of // the chromeless player, we could load videos if (ytplayer.isPlayerLoaded()) { ytplayer.addEventListener("onStateChange", onPlayerStateChange); ytplayer.addEventListener("onError", onPlayerError); clearInterval(loadInterval); } } function onPlayerStateChange(newState:Number) { trace("New player state: "+ newState); } function onPlayerError(errorCode:Number) { trace("An error occurred: "+ errorCode); } // create a MovieClipLoader to handle the loading of the player var ytPlayerLoader:MovieClipLoader = new MovieClipLoader(); ytPlayerLoader.addListener(ytPlayerLoaderListener); // load the player ytPlayerLoader.loadClip("http://www.youtube.com/v/pv5zWaTEVkI", ytplayer); can anyone help me on how to get the id of the video (for example: pv5zWaTEVkI) from the feed? Or how to send a query from flash which will return the video url/id as opposed to the url of a feed. Any help would be much appreciated as my hand in rather soon. Thanks

  • Altering lazy-loaded object's private variables

    - by Kevin Pang
    I'm running into an issue with private setters when using NHibernate and lazy-loading. Let's say I have a class that looks like this: public class User { public int Foo {get; private set;} public IList<User> Friends {get; set;} public void SetFirstFriendsFoo() { // This line works in a unit test but does nothing during a live run with // a lazy-loaded Friends list Users(0).Foo = 1; } } The SetFirstFriendsFoo call works perfectly inside a unit test (as it should since objects of the same type can access each others private properties). However, when running live with a lazy-loaded Friends list, the SetFirstFriendsFoo call silently fails. I'm guessing the reason for this is because at run-time, the Users(0).Foo object is no longer of type User, but of a proxy class that inherits from User since the Friends list was lazy-loaded. My question is this: shouldn't this generate a run-time exception? You get compile-time exceptions if you try to access another class's private properties, but when you run into a situation like this is looks like the app just ignores you and continues along its way.

  • UITableView madness

    - by kesrut
    Hello, I'm new to iPhone application development. I'm trying to understand how to use UITableView. I'm wrote simple code: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 1 ; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MyIdentifier = @"MyIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease]; } cell.textLabel.text = @"Hello"; return cell; } UITable shows content, but if i'm drag table contents my application terminates. You can see video: http://www.youtube.com/watch?v=TucTVJVhSD0 I tried to everything with array: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1 ; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [hello count] ; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MyIdentifier = @"MyIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease]; } cell.textLabel.text = [hello objectAtIndex:indexPath.row]; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [tableView deselectRowAtIndexPath:indexPath animated:NO]; NSLog(@"Selected") ; } - (void) awakeFromNib { hello = [[NSArray alloc] initWithObjects:@"hello", @"world", @"end", nil]; } // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; } Content is shown and if I'm selecting item i'm getting: [Session started at 2010-03-16 19:21:48 +0200.] 2010-03-16 19:21:52.295 ViewTest[1775:207] * -[ViewTestViewController respondsToSelector:]: message sent to deallocated instance 0x3911ec0 I'm total new to iPhone programming. And as i see everything i do - i'm just getting application terminated ..

  • IPhone SDK - Leaking Memory with performSelectorInBackground

    - by Steblo
    Hi. Maybe someone can help me with this strange thing: If a user clicks on a button, a new UITableView is pushed to the navigation controller. This new view is doing some database querying which takes some time. Therefore I wanted to do the loading in background. What works WITHOUT leaking memory (but freezes the screen until everything is done): WorkController *tmp=[[WorkController alloc] initWithStyle:UITableViewStyleGrouped]; self.workController=tmp; [tmp release]; [self.workController loadList]; // Does the DB Query [self.workController pushViewController:self.workController animated:YES]; Now I tried to do this: // Show Wait indicator .... WorkController *tmp=[[WorkController alloc] initWithStyle:UITableViewStyleGrouped]; self.workController=tmp; [tmp release]; [self performSelectorInBackground:@selector(getController) withObject:nil]; } -(void) getController { [self.workController loadList]; // Does the DB Query [self.navigationController pushViewController:self.workController animated:YES]; } This also works but is leaking memory and I don't know why ! Can you help ? By the way - is it possible for an App to get into AppStore with a small memory leak ? Or will this be checked first of all ? Thanks in advance !

  • Compiled Haskell libraries with FFI imports are invalid when imported into GHCI

    - by John Millikin
    I am using GHC 6.12.1, in Ubuntu 10.04 When I try to use the FFI syntax for static storage, only modules running in interpreted mode (ie GHCI) work properly. Compiled modules have invalid pointers, and do not work. I'd like to know whether anybody can reproduce the problem, whether this an error in my code or GHC, and (if the latter) whether it's a known issue. I'm using sys_siglist because it's present in a standard library on my system, but I don't believe the actual storage used matters (I discovered this while writing a binding to libidn). If it helps, sys_siglist is defined in <signal.h> as: extern __const char *__const sys_siglist[_NSIG]; I thought this type might be the problem, so I also tried wrapping it in a plain C procedure: #include<stdio.h> const char **test_ffi_import() { printf("C think sys_siglist = %X\n", sys_siglist); return sys_siglist; } However, importing that doesn't change the result, and the printf() call prints the same pointer value as show siglist_a. My suspicion is that it's something to do with static and dynamic library loading. Update: somebody in #haskell suggested this might be 64-bit specific; if anybody tries to reproduce it, can you mention your architecture and whether it worked in a comment? Code as follows: -- A.hs {-# LANGUAGE ForeignFunctionInterface #-} module A where import Foreign import Foreign.C foreign import ccall "&sys_siglist" siglist_a :: Ptr CString -- -- B.hs {-# LANGUAGE ForeignFunctionInterface #-} module B where import Foreign import Foreign.C foreign import ccall "&sys_siglist" siglist_b :: Ptr CString -- -- Main.hs {-# LANGUAGE ForeignFunctionInterface #-} module Main where import Foreign import Foreign.C import A import B foreign import ccall "&sys_siglist" siglist_main :: Ptr CString main = do putStrLn $ "siglist_a = " ++ show siglist_a putStrLn $ "siglist_b = " ++ show siglist_b putStrLn $ "siglist_main = " ++ show siglist_main peekSiglist "a " siglist_a peekSiglist "b " siglist_b peekSiglist "main" siglist_main peekSiglist name siglist = do ptr <- peekElemOff siglist 2 str <- maybePeek peekCString ptr putStrLn $ "siglist_" ++ name ++ "[2] = " ++ show str I would expect something like this output, where all pointer values identical and valid: $ runhaskell Main.hs siglist_a = 0x00007f53a948fe00 siglist_b = 0x00007f53a948fe00 siglist_main = 0x00007f53a948fe00 siglist_a [2] = Just "Interrupt" siglist_b [2] = Just "Interrupt" siglist_main[2] = Just "Interrupt" However, if I compile A.hs (with ghc -c A.hs), then the output changes to: $ runhaskell Main.hs siglist_a = 0x0000000040378918 siglist_b = 0x00007fe7c029ce00 siglist_main = 0x00007fe7c029ce00 siglist_a [2] = Nothing siglist_b [2] = Just "Interrupt" siglist_main[2] = Just "Interrupt"

  • Using Pylint with Django

    - by rcreswick
    I would very much like to integrate pylint into the build process for my python projects, but I have run into one show-stopper: One of the error types that I find extremely useful--:E1101: *%s %r has no %r member*--constantly reports errors when using common django fields, for example: E1101:125:get_user_tags: Class 'Tag' has no 'objects' member which is caused by this code: def get_user_tags(username): """ Gets all the tags that username has used. Returns a query set. """ return Tag.objects.filter( ## This line triggers the error. tagownership__users__username__exact=username).distinct() # Here is the Tag class, models.Model is provided by Django: class Tag(models.Model): """ Model for user-defined strings that help categorize Events on on a per-user basis. """ name = models.CharField(max_length=500, null=False, unique=True) def __unicode__(self): return self.name How can I tune Pylint to properly take fields such as objects into account? (I've also looked into the Django source, and I have been unable to find the implementation of objects, so I suspect it is not "just" a class field. On the other hand, I'm fairly new to python, so I may very well have overlooked something.) Edit: The only way I've found to tell pylint to not warn about these warnings is by blocking all errors of the type (E1101) which is not an acceptable solution, since that is (in my opinion) an extremely useful error. If there is another way, without augmenting the pylint source, please point me to specifics :) See here for a summary of the problems I've had with pychecker and pyflakes -- they've proven to be far to unstable for general use. (In pychecker's case, the crashes originated in the pychecker code -- not source it was loading/invoking.)
