  • dynamic JSF composite component styling/rendering

    - by Checkoff
    I've a little problem with a composite component. This component's implementation looks like: <composite:implementation> <h:outputStylesheet name="foo.css" library="bar"/> <div id="#{cc.clientId}"> <composite:insertChildren/> </div> </composite:implementation> It is included dynamically into a facelet page which include this component with JSTL core tags. The facelet page is similar to the following one. <h:panelGroup id="viewport" layout="block"> <c:if test="#{controller.object != null}"> <c:forEach items="#{controller.object.elements}" var="element"> <c:if test="#{element.type == 'type1'}"> <my:componentTypeOne id="#{element.id}"/> </c:if> <c:if test="#{element.type == 'type2'}"> <my:componentTypeTwo id="#{element.id}"/> </c:if> </c:forEach> </c:if> </h:panelGroup> So when I only render the viewport of the page the components are rendered but without the stylesheet defined within the composite component my:component. Is there any way to include the stylesheet on the fly without rendering the whole page? EDIT: extension of the example code..

  • What is the right pattern for a async data fetching method in .net async/await

    - by s093294
    Given a class with a method GetData. A few other clients call GetData, and instead of it fetching data each time, i would like to create a pattern where the first call starts the task to get the data, and the rest of the calls wait for the task to complete. private Task<string> _data; private async Task<string> _getdata() { return "my random data from the net"; //get_data_from_net() } public string GetData() { if(_data==null) _data=_getdata(); _data.wait(); //are there not a problem here. cant wait a task that is already completed ? if(_data.status != rantocompletion) _data.wait() is not any better, it might complete between the check and the _data.wait? return _data.Result; } How would i do the pattern correctly? (Solution) private static object _servertime_lock = new object(); private static Task<string> _servertime; private static async Task<string> servertime() { try { var thetvdb = new HttpClient(); thetvdb.Timeout = TimeSpan.FromSeconds(5); // var st = await thetvdb.GetStreamAsync("http://www.thetvdb.com/api/Updates.php?type=none"); var response = await thetvdb.GetAsync("http://www.thetvdb.com/api/Updates.php?type=none"); response.EnsureSuccessStatusCode(); Stream stream = await response.Content.ReadAsStreamAsync(); XDocument xdoc = XDocument.Load(stream); return xdoc.Descendants("Time").First().Value; } catch { return null; } } public static async Task<string> GetServerTime() { lock (_servertime_lock) { if (_servertime == null) _servertime = servertime(); } var time = await _servertime; if (time == null) _servertime = null; return time; }

  • How to customize the process employed by WCF when serializing contract method arguments?

    - by mark
    Dear ladies and sirs. I would like to formulate a contrived scenario, which nevertheless has firm actual basis. Imagine a collection type COuter, which is a wrapper around an instance of another collection type CInner. Both implement IList (never mind the T). Furthermore, a COuter instance is buried inside some object graph, the root of which (let us refer to it as R) is returned from a WCF service method. My question is how can I customize the WCF serialization process, so that when R is returned, the request to serialize the COuter instance will be routed through my code, which will extract CInner and pass it to the serializer instead. Thus the receiving end still gets R, only no COuter instance is found in the object graph. I hoped that http://stackoverflow.com/questions/2220516/how-does-wcf-serialize-the-method-call will contain the answer, unfortunately the article mentioned there (http://msdn.microsoft.com/en-us/magazine/cc163569.aspx) only barely mentions that advanced serialization scenarios are possible using IDataContractSurrogate interface, but no details are given. I am, on the other hand, would really like to see a working example. Thank you very much in advance.

  • Why is Core Data not persisting these changes to disk?

    - by scott
    I added a new entity to my model and it loads fine but no changes made in memory get persisted to disk. My values set on the car object work fine in memory but aren't getting persisted to disk on hitting the home button (in simulator). I am using almost exactly the same code on another entity in my application and its values persist to disk fine (core data - sqlite3); Does anyone have a clue what I'm overlooking here? Car is the managed object, cars in an NSMutableArray of car objects and Car is the entity and Visible is the attribute on the entity which I am trying to set. Thanks for you assistance.

  • C# Web Service gets stuck waiting for lock, does not return

    - by blue
    We have a C#(2.0) application which talks to our server(in java) via web services.

  • ListBox selector odd behavior when there are dupes

    - by byte1918
    I'm working on a bigger project atm, but I made this simple example to show you what happens.. using System.Collections.Generic; using System.Windows; namespace txt { public partial class MainWindow { public MainWindow() { InitializeComponent(); } private void Window_Loaded(object sender, RoutedEventArgs e) { var obsLst = new List<Info> { new Info { name = "asd" }, new Info { name = "asd" }, new Info { name = "asd" }, new Info { name = "asd" } }; var temp = new List<Info>(); for (var i = 1; i <= 3; i++) { temp.Add(obsLst[0]); //I add 3 of the same item from obsLst to temp } lst.DataContext = temp; //lst = ListBox } } public class Info { public string name { get; set; } } } The ListBox ItemsSource is set to {Binding}.. When I start the application I get 3 txt.Info objects displayed and if I click any of them, 2 or even all of them get selected aswell. From my understanding the problem relies in the fact that the listbox selector cannot differentiate between the items and therefor doesn't know which one I selected. Here's a picture of what it looks like.. I only clicked on the second txt.Info item. I found a solution where someone said that I have to specify the DisplayMemberPath, but I can't really do that in the other project because I have a datatemplate for the object. Any ideas on how I could fix this would be great.. Thx in advance.

  • How to suppress jqgrid from initially loading data?

    - by Steve Johnston
    I have a page that has a couple of jqGrids on it, along with a few other fields. I want to make one AJAX call myself that pulls back a JSON object that has the data that should be used to fill the entire page. So, I would like to make the call myself, populate the "other fields" and then pull a couple of collections off of the main JSON object that was returned and populate each of the jqGrids with those collections "manually". I have this much working, but I can't get jqGrid to stop attempting to make an AJAX request itself. Shouldn't there be a way to tell jqGrid to NOT attempt an AJAX call when it is initialized? I found a similar question asked here: http://stackoverflow.com/questions/1850159/how-to-suppress-jqgrid-from-initially-loading-data But I don't have the option that solved it for the poster. It seems pretty logical to me that some people may want to use this plugin without having the table attempt to get its own data upon initialization. Am I missing an option somewhere in the documentation (wiki - options)? Thanks.

  • ASP.NET MVC 2 - How do I use DropDownListFor ?

    - by SLC
    I have a simple model / view with things like Username, Password etc. and use helpers fine to hook it up. I now have a field called "NumberOfChildren". I want to store a number in it (int) and I want it render a dropdown box containing "None", "1", "2" etc. My thoughts would be that the model would have a list or a method that returns a list, so I can specify the values such as NumberOfChildren_List that I put the data into, and then DropDownListFor pulls that list and renders it, matching the value to the value of the item in the dropdown. However after spending about 30 minutes on trying to figure out how on earth it works, I gave up and decided to ask here. Any ideas? Edit: Here's some code... <%: Html.DropDownListFor(m => m.NumberOfChildren, new SelectList(Model.NumberOfChildrenListValues))%> and in the model [Required] [DisplayName("How many children do you have?")] public string NumberOfChildren { get; set; } public IEnumerable<string> NumberOfChildrenListValues { get { List<string> list = new List<string>() { "None", "1", "2" }; return list; } set { } } I get an object not set to instance of object error though. Ideas?

  • implementing stretchable dialog borders in iphone sdk

    - by Joey
    Hi, I want to implement dialog borders that scale to the size I require the dialog to be. Perhaps there is a better more conventional name for this sort of thing. If there is, if someone would edit the title, that'd be great. Anyhow, I'd like to do this so I can have dialogs of any size without the visual artifacts that come with scaling border art to small, large, or wacky unproportional dimentions. I have a few ideas on how this is done, but am not sure which is better for iphone. I have a few questions. 1) Should I make a containing view object that basically overloads its drawRect method and draws the images where they should be at their appropriate scale when the method is called, or should I main a containing view object that simply contains 8 UIImageViews? I suspect the latter approach won't work if I need to actively scale the resulting dialog class like in an animation. 1b) If overloading drawRect is the way to go, does someone have some sample code or a link to an example that demonstrates drawing an image directly from drawRect()? 2) Is it generally better to create a) a 3 x 3 image where the segments are in their appropriate 1x1 grid of the image? If so, is it simple to draw from a portion of this image onto my target view in drawRect (if the former assumption is correct that I should use drawRect)? b) The pieces separately in 8 different files?

  • How to use a getter with a nullable?

    - by Desmond Lost
    I am reading a bunch of queries from a database. I had an issue with the queries not closing, so I added a CommandTimeout. Now, the individual queries read from the config file each time they are run. How would I make the code cache the int from the config file only once using a static nullable and getter. I was thinking of doing something along the lines of: static int? var; get{ var = null; if (var.HasValue) ...(i dont know how to complete the rest) My actual code: private object ExecuteQuery(string dbConnStr, bool fixIt) { object result = false; using (SqlConnection connection = new SqlConnection(dbConnStr)) { connection.Open(); using (SqlCommand sqlCmd = new SqlCommand()) { AddSQLParms(sqlCmd); sqlCmd.CommandTimeout = 30; sqlCmd.CommandText = _cmdText; sqlCmd.Connection = connection; sqlCmd.CommandType = System.Data.CommandType.Text; sqlCmd.ExecuteNonQuery(); } connection.Close(); } return result; }}

  • Design patterns for Agent / Actor based concurrent design.

    - by nso1
    Recently i have been getting into alternative languages that support an actor/agent/shared nothing architecture - ie. scala, clojure etc (clojure also supports shared state). So far most of the documentation that I have read focus around the intro level. What I am looking for is more advanced documentation along the gang of four but instead shared nothing based. Why ? It helps to grok the change in design thinking. Simple examples are easy, but in a real world java application (single threaded) you can have object graphs with 1000's of members with complex relationships. But with agent based concurrency development it introduces a whole new set of ideas to comprehend when designing large systems. ie. Agent granularity - how much state should one agent manage - implications on performance etc or are their good patterns for mapping shared state object graphs to agent based system. tips on mapping domain models to design. Discussions not on the technology but more on how to BEST use the technology in design (real world "complex" examples would be great).

  • ASP.NET MVC3 - Bug using Javascript

    - by ebb
    Hey there, I'm trying to use Ajax.BeginForm() to POST A Json result from my controller (I'm using MVC3). When the Json result is called it should be sent to a javascript function and extract the object using "var myObject = content.get_response().get_object();", However it just throws a "Microsoft JScript runtime error: Object doesn't support this property or method" when trying to invoke the Ajax POST. My code: Controller: [HttpPost] public ActionResult Index(string message) { return Json(new { Success = true, Message = message }); } View: <!DOCTYPE html> <html> <head> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script> <script type="text/javascript"> function JsonAdd_OnComplete(mycontext) { var myObject = mycontext.get_response().get_object(); alert(mycontext.Message); } </script> </head> <body> <div> @using(Ajax.BeginForm("Index", "Home", new AjaxOptions() { HttpMethod = "POST", OnComplete = "JsonAdd_OnComplete" })) { @Html.TextBox("message") <input type="submit" value="SUBMIT" /> } </div> </body> </html> The strange thing is that the exactly same code works in MVC2 - Is this a bug, or have I forgot something?

  • Python unittest (using SQLAlchemy) does not write/update database?

  • Java KeyListener in separate class

    - by Chris
    So I have my main class here, where basically creates a new jframe and adds a world object to it. The world object is basically where all drawing and keylistening would take place... public class Blobs extends JFrame{ public Blobs() { super("Blobs :) - By Chris Tanaka"); setVisible(true); setResizable(false); setSize(1000, 1000); setIgnoreRepaint(true); setDefaultCloseOperation(EXIT_ON_CLOSE); add(new World()); } public static void main(String[] args) { new Blobs(); } } How exactly would you get key input from the world class? (So far I have my world class extending a jpanel and implementing a keylistener. In the constructor i addKeyListener(this). I also have these methods since they are auto implemented: public void keyPressed(KeyEvent e) { if (e.getKeyCode() == KeyEvent.VK_W) System.out.println("Hi"); } public void keyReleased(KeyEvent e) {} public void keyTyped(KeyEvent e) {} However this does not seem to work?

  • Trying to write up a C daemon, but don't know enough C to continue

    - by JamesM-SiteGen
    Okay, so I want this daemon to run in the background with little to no interaction. I plan to have it work with Apache, lighttpd, etc to send the session & request information to allow C to generate a website from an object DB, saving will have to be an option so, you can start the daemon with an existing DB but will not save to it unless you login to the admin area and enable, and restart the daemon. Summary of the daemon: Load a database from file. Have a function to restart the daemon. Allow Apache, lighttpd, etc to get necessary data about the request and session. A varible to allow the database to be saved to the file, otherwise it will only be stored in ram. If it is set to save back to the file, then only have neccessary data in ram. Use sql-light for the database file. Build a webpage from some template files. $(myVar) for getting variables. Get templates from a directory. ./templates/01-test/{index.html,template.css,template.js} Live version of the code and more information: http://typewith.me/YbGB1h1g1p Also I am working on a website CMS in php, but I am tring to switch to C as it is faster than php. ( php is quite fast, but the fact that making a few mySQL requests for every webpage is quite unefficent and I'm sure that it can be far better, so an object that we can recall data from in C would have to be faster ) P.S I am using Arch-Linux not MS-Windows, with the package group base-devel for the common developer tools such as make and makepgk. Edit: Oupps, forgot the question ;) Okay, so the question is, how can I turn this basic C daemon into a base to what I am attempting to do here?

  • Getting all objects with a certain element inside a collection of strings with criteria API.

    - by Jens Jansson
    Hey. I'm trying to build a Hibernate Criteria query to find entities that have a specific element inside a collection. We can take as an example a Book -object that looks like this: public class Book { private Long id; private String title; private Set<String> authors = new HashSet<String>(); } The entity is mapped like this: <class name="Book" table="Book"> <id name="id" column="BOOK_ID"> <generator class="native"/> </id> <property name="title"/> <set name="authors" table="Book_Authors"> <key column="BOOK_ID"/> <element type="string" column="AUTHORS"/> </set> </class> Now I would like to find out which books are written by Matt. With pure SQL I can do a query like this: String author = "Matt"; String query = "SELECT * FROM Book " + "WHERE BOOK_ID IN " + "(SELECT BOOK_ID FROM Book_Authors " + "WHERE authors = :author )"; List<Book> result = session.createSQLQuery(query) .addEntity(Book.class) .setParameter("author", author) .list(); This works all good and well, and I get out all books that Matt has been a part of writing. The project I work in, however, uses the Criteria API instead of raw SQL, and I haven't found a way to express the same query in that form. I've taken a look on the Restrictions API and the closest I've found is Restions.in(propertyName, collection) but that works the other way around (one value in object, many values to match against). Any ideas?

  • Getting wierd issue with TO_NUMBER function in Oracle

    - by Fazal
    I have been getting an intermittent issue when executing to_number function in the where clause on a varchar2 column if number of records exceed a certain number n. I used n as there is no exact number of records on which it happens. On one DB it happens after n was 1 million on another when it was 0.1. million. E.g. I have a table with 10 million records say Table Country which has field1 varchar2 containing numberic data and Id If I do a query as an example select * from country where to_number(field1) = 23 and id 1 and id < 100000 This works But if i do the query select * from country where to_number(field1) = 23 and id 1 and id < 100001 It fails saying invalid number Next I try the query select * from country where to_number(field1) = 23 and id 2 and id < 100001 It works again As I only got invalid number it was confusing, but in the log file it said Memory Notification: Library Cache Object loaded into SGA Heap size 3823K exceeds notification threshold (2048K) KGL object name :with sqlplan as ( select c006 object_owner, c007 object_type,c008 object_name from htmldb_collections where COLLECTION_NAME='HTMLDB_QUERY_PLAN' and c007 in ('TABLE','INDEX','MATERIALIZED VIEW','INDEX (UNIQUE)')), ws_schemas as( select schema from wwv_flow_company_schemas where security_group_id = :flow_security_group_id), t as( select s.object_owner table_owner,s.object_name table_name, d.OBJECT_ID from sqlplan s,sys.dba_objects d It seems its related to SGA size, but google did not give me much help on this. Does anyone have any idea about this issue with TO_NUMBER or oracle functions for large data?

  • How to: generate UnhandledException?

    - by serhio
    I use this code to catch the WinForm application UnhandledException. [STAThread] static void Main(string[] args) { // Add the event handler for handling UI thread exceptions to the event. Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException); // Set the unhandled exception mode to force all Windows Forms errors // to go through our handler. Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException); // Add the event handler for handling non-UI thread exceptions to the event. AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); try { Application.Run(new MainForm()); } catch.... There I will try to restart the application. Now my problem is to simulate a exception like this. I tried before try (in main): throw new NullReferenceException("test"); VS caught it. Tried also in MainForm code with button : private void button1_Click(object sender, EventArgs ev) { ThreadPool.QueueUserWorkItem(new WaitCallback(TestMe), null); } protected void TestMe(object state) { string s = state.ToString(); } did not help, VS caught it, even in Release mode. How should I, finally, force the application generate UnhandleldException? Will I be able to restart the application in CurrentDomain_UnhandledException?

  • activemerchant PayPalExpress transaction is invalid

    - by Ameya Savale
    I am trying to integrate activemerchant into my ruby on rails application. This is my controller where I get the purchase attirbutes and create a PaypalExpressResponse object def checkout total_as_cents, purchase_params = get_setup_params(Schedule.find(params[:schedule]), request) setup_response = @gateway.setup_purchase(total_as_cents, purchase_params) redirect_to @gateway.redirect_url_for(setup_response.token) end @gateway is my PaypalExpressGateway object which I create using this method in my controller def assign_gateway @gateway = PaypalExpressGateway.new( :login => api_user, :password => api_pass, :signature => api_signature ) end I got the api_user, api_pass, and api_signature values from my developer.paypal.com account, when I logged in for the first time there was already a sandbox user created as a merchant which is where I got the api credentials from. And finally here is my get_setup_params method: def get_setup_params(schedule, request) purchase_params = { :ip => request.remote_ip, :return_url => url_for(:action => 'review', :only_path => false, :sched => schedule.id), :cancel_return_url => register_path, :allow_note => true, :item => schedule.id } return to_cents(schedule.fee), purchase_params end How ever when I click on the checkout button, I get redirected to a sandbox paypal page saying "This transaction is invalid. Please return to the recipient's website to complete your transaction using their regular checkout flow." I'm not sure exactly what's wrong, I think the problem lies in the credentials but don't know why. Any help will be appreciated. One other point, I'm running this in my development environment so I have put this in my config file config.after_initialize do ActiveMerchant::Billing::Base.mode = :test end UPDATE Found out what the problem was, my return cancel url was invalid instead of using register_path, I used url_for(action: "action-name", :only_path => false) this answer helped me Rails ActiveMerchant - Paypal Express Checkout Error even though I wasn't able to see the output of the response like the person has managed to do

  • What changes in Core Data after a save?

    - by Splash6
    I have a Core Data based mac application that is working perfectly well until I save a file. When I save a file it seems like something changes in core data because my original fetch request no longer fetches anything. This is the fetch request that works before saving but returns an empty array after saving. NSEntityDescription *outputCellEntityDescription = [NSEntityDescription entityForName:@"OutputCell" inManagedObjectContext:[[self document] managedObjectContext]]; NSFetchRequest *outputCellRequest = [[[NSFetchRequest alloc] init] autorelease]; [outputCellRequest setEntity:outputCellEntityDescription]; NSPredicate *outputCellPredicate = [NSPredicate predicateWithFormat:@"(cellTitle = %@)", outputCellTitle]; [outputCellRequest setPredicate:outputCellPredicate]; NSError *outputCellError = nil; NSArray *outputCellArray = [[[self document] managedObjectContext] executeFetchRequest:outputCellRequest error:&outputCellError]; I have checked with [[[self document] managedObjectContext] registeredObjects] to see that the object still exists after the save and nothing seems to have changed and the object still exists. It is probably something fairly basic but does anyone know what I might be doing wrong? If not can anyone give me any pointers to what might be different in the Core Data model after a save so I might have some clues why the fetch request stops working after saving?

  • Textures in Opengl ES 2 not working properly

    - by Adl
    Hi! I'm working with Opengl ES 2 on iphone and right now I am trying to get my textures working on my objects. I'm using .obj files and all the data in them are correct. I have written a parser myself to retrieve all data, I convert it to static arrays in C. I discard the material properties for now, only getting the image path from the .mtl files manually. I have an object with 336 triangles, making this non-trivial to observe, with appertaining vertices, vertex faces and texture coordinates (u,v). Passing all data into the shaders, the resulting image is this: http://img530.imageshack.us/img530/9637/pic1io.png http://img404.imageshack.us/img404/7358/pic2pg.png But it should look like this (Displaying it in an object viewer). Please ignore the material properties. http://img16.imageshack.us/img16/1401/pic3cq.png Using this image as a texture: http://img217.imageshack.us/img217/1300/shirtdiffuse.png I'm thinking it might have to do with texture coordinate faces ? It is defined in my .obj file, and I'm not using them at all. In books and tutorials I have not found anything concerning this. Regards Niclas
