NSFetchedResultsController Crashes When Navigating from One UITableViewController to Another

- by wgpubs

In my core data model I have a Person entity that has a "to many" relationship a Course entity (I also have an inverse "to one" relationship from Course to Person). Now I have a subclassed UITableViewController that uses a NSFetchedResultsController to display Person objects which works fine. I have this set up so that when you click on a Person it publishes another subclassed UITableViewController that uses a NSFetchedController as well to display the Courses associated to the person. PROBLEM: I get this exception whenever I click on the Person and attempt to display the Course UITableViewController ... "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'keypath name not found in entity <NSSQLEntity Course id=2>'" Any ideas on how to resolve or troubleshoot? The code between the two ViewControllers is almost identical except for the NSFetchedResultsController being configured for "Person" entities in one and "Course" entities in another

Android: Image displayed at Webview from Url with high quality loss

- by Merlino

I want to display an image from an url with an Webview at Android. With Android phones with Version 1.5 and 1.6 there is no problem. but the same pic and the same code on an AndroidPhone with Version 2.0 and the pic is totaly pixelated. Like Android is resizing the image first to a smaller one and then resizing it back to "normal" size. Unfortunately its important to display the pic without any quality loss. I tried to integrate it in the sourcefolder to show it as an normal image, but at Android 2.0 i get an exception because the image is to big. (At Android 1.6 there is no problem) Any ideas how i can display the image without quality loss with Android 2.0 ?

Actual table Vs. Div table

- by omfgroflmao

This <table> <tr> <td>Hello</td> <td>World</td> </tr> </table> Can be done with this: <div> <div style="display: table-row;"> <div style="display: table-cell;">Hello</div> <div style="display: table-cell;">World</div> </div> </div> Now, is there any difference between these two in terms of performance and/or render speed or they're just the same?

App store name and info.plist

- by user346194

Hi guys, I've just completed my first app and having tested I'm ready for submission. However, despite numerous web searches and reading, I'm struggling to finalise the method required to enable me to have a different name on the app store to the name that appears under the app on the device home screen. In the plist.info file there is reference to bundle display name, executable name, bundle name, bundle identifier, product name etc. So, for example, say I would like the app store name to display as: HELLO WORLD and I would like the name below the icon on the device home screen to display as: HELLO How should I enter the data in the plist.info file to achieve the above? Many thanks in advance for your help. Gav.

Problems running Java SWT application. Is this something to do with 64 vs 32-bit libraries?

- by ?????

I'm getting started with SWT Exception in thread "main" java.lang.UnsatisfiedLinkError: no swt-cocoa-3557 or swt-cocoa in swt.library.path, java.library.path or the jar file at org.eclipse.swt.internal.Library.loadLibrary(Unknown Source) at org.eclipse.swt.internal.Library.loadLibrary(Unknown Source) at org.eclipse.swt.internal.C.<clinit>(Unknown Source) at org.eclipse.swt.internal.cocoa.NSThread.isMainThread(Unknown Source) at org.eclipse.swt.graphics.Device.<init>(Unknown Source) at org.eclipse.swt.widgets.Display.<init>(Unknown Source) at org.eclipse.swt.widgets.Display.<init>(Unknown Source) at org.eclipse.swt.widgets.Display.getDefault(Unknown Source) at com.astrobetty.getotagdesktop.MainUIWindow.main(MainUIWindow.java:110) I've carefully followed the directions here http://www.eclipse.org/swt/eclipse.php I can see libswt-awt-cocoa-3557.jnilib, libswt-cocoa-3557.jnilib, libswt-pi-cocoa-3557.jnilib clearly listed under "Referenced Libraries" in my Eclipse package explorer. Presumably, that should make them available on the classpath when I select the java module that contains "main" and do a "run as" application. What's the problem? I suspect it may be related to 64-bit vs 32-bit VMs....

Zend currency custom format like "$ 1,234.56 USD"

- by Jorre

I'm using the zend currency module to manage currencies in a web app. I can't figure out how to create a custom format for my currencies, since there are no examples on the documentation pages: http://framework.zend.com/manual/en/zend.currency.options.html From what I read there, I could use the format parameter to set a format, but I can't find a way how. Does anyone have a good code example for this problem? currently I do the following: $currency->setFormat(array (display' => Zend_Currency::USE_SYMBOL)); That works to display only the symbol, but I'm also interested in putting an extra space after or before the symbol and to display currencies like this: "$ 1,234.56 USD" "€ 1.234,56 EUR"

How to rotate 4 images, fading between each one?

- by Darryl Hein

I have 4 images, which I want to fade between each other in a loop. I have something like the following: <img src="/images/image-1.jpg" id="featureImg1" /> <img src="/images/image-2.jpg" id="featureImg2" style="display:none;" /> <img src="/images/image-3.jpg" id="featureImg3" style="display:none;" /> <img src="/images/image-4.jpg" id="featureImg4" style="display:none;" /> I am up for revisions to the HTML, although I cannot use absolute positioning in this case. I am using jQuery else where on the site, so it's available. I also need to deal with an image not being loaded right away as the images are larger.

Zend RegEx Validator error message issue

- by Mallika Iyer

Hello, I'm validating a text field in my form as follows: $name = new Zend_Form_Element_Text('name'); $name->setLabel('First Name:') ->setRequired(true) ->addFilter(new Zend_Filter_StringTrim()) ->addValidator('regex',true,array('/^[(a-zA-Z0-9)]+$/')) ->addErrorMessage('Please enter a valid first name'); What I'm trying to accomplish is - how can i display a meaningful error message? Eg: If first name is 'XYZ-', how can i display '- is not allowed in first name.' Is there a way I can access what character the regex is failing for? Would you recommend something else altogether? I thought about writing a custom validator but the regex is pretty simple, so I don't see the point. I couldn't find a decent documentation for the zend 'regex' validator anywhere. If I don't override the default error message, I simple get something like : ';;;hhbhbhb' does not match against pattern '/^[(a-zA-Z0-9)]+$/' - which I obviously don't want to display to the user. I'd appreciate your inputs.

jQuery CSS Custom Flyout Menu Styling Issue

- by aherrick

I'm close to nailing this flyout menu I have been working on, just have a couple of current pain points. I'm trying to get left/right padding on my submenu items, as you can see I am not quite there. Also when the first submenu is displayed, I want to create a bit of a gap between the first row of list items and the child. Below is my current code and a screen shot displaying what I want.

AS3 Event Bubbling outside of the Scenegraph/DisplayList

- by Brian Heylin

Hi just wondering if it is possible to take advantage of event bubbling in non display list classes in AS3. For example in the model of an application where there is a City class that contains many Cars. What methods are there to attach an event listener to a City object and receive events that bubble up from the child Cars. To clarify The City and Car objects are not part of the display list, they are not DisplayObjects. So can bubbling be implemented outside of the display list somehow? As far as I know, this is not possible without manually attaching event listeners to each Car object and re dispatching the event from the City object. Anyone else have a cleaner solution?

Retrieving related data in the Symfony Admin Generator

- by bjoern

I have a problem with the Admin Generator. The Table of Pages have the column sf_guard_user_id. The rest of the table looks as this part of the generator.yml in the line display, list: title: Pages display: [=title, sfGuardUser, views, state, privacy, created_at, updated_at] sort: [created_at, desc] fields: sfGuardUser: { label: Author } created_at: { label: Published, date_format: dd.MM.y } updated_at: { label: Updated, date_format: dd.MM.y } table_method: retrieveUserList Now the sf_guard_user_id is been replaced and the username ist displayed. Don't get me wrong, that works fine. But how can I get other variables from the sfGuarsUser relation? When I only add salt or another variable to display I get this, Unknown record property / related component "salt" on "simplePage" But why?

Smarty debug mode not displaying included templates.

- by Kyle Sevenoaks

On www.euroworker.no/order I have set Smarty's debug mode on with {debug output=html} in the header, so it will debug every page. But it says: Smarty Debug Console included templates & config files (load time in seconds): no templates included And after a list of template variables, {$cart} Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 561962 bytes) in /home/euroworkerno/www/library/smarty/libs/plugins/modifier.debug_print_var.php on line 30 It also doesn't display a list of templates for any url.. This is strange, can anyone point me to why it won't display the lit of .tpls? I need to find some HTML comments that someone has left in to rid IE of a display bug. Thanks.

Get "As low as" price for bundle product in Magento

- by dardub

I'm trying to display a list of bundled products using my custom template. I'm not able to display the dynamic price of the bundle product. Previously for simple products I used: $product->getPrice(); which worked, but it just displays $0.00 for bundle items. looking at ../catalog/products/list.phtml I tried $this->$getPriceHtml($product, true); after extending my block to Mage_Catalog_Block_Product_Abstract I got simple products working again, but bundle products still show $0.00 Is there another way to display the as low as price for dynamic bundle prices? I cleared cache and reindexed and all that good stuff. The price shows up correctly under the default category list, just not under my custom page.

Returning unique values of a multi-dimensional array with CodeIgniter PHP

- by Michael Bradley

Hi - I'm developing a property rentals website. The search results page will contain a list of property results. It is my intention to redefine the results, say by town, country, property type etc. So let's say for example the user searches 'France'. All of the relative properties will be returned and displayed in a list. However, I also need to reuse this array, to display only unique town names from the search results array. e.g. Montpellier, Lyon, Rennes, Nice etc. The idea is when use user click on 'Nice', only the 'Nice' properties would return. I would also like to display how many properties are in that town. The closest example as to what I want to achieve. http://www.miaandmaggie.com/dog-collars-leashes.html Any ideas how I can use my search array to display the unique towns of the search? Many thanks!

In C#, how do you send a refresh/repaint message to a WPF grid or canvas?

- by xarzu

How do you send a refresh message to a WPF grid or canvas? In other words, I have noticed while in debug mode, I can write code that sends a line to the display and then, if that line is not right, I can adjust it -- but the previous line is still there. Now, the code I am writing sends information to the display based on what the user clicks. So this must mean that the display is not refreshed each time a new set of lines and boxes and text goes to the grid or canvas in WPF. Using C# code, how do you send a refresh/repaint message to a WPF grid or canvas?

Default login popup for web sites

Hi. I am trying to build a web site with ASP.NET MVC, I'm new to this. My question is: how can I display the default login dialog? I am not referring to a custom dialog, like the jQuery Dialog, there is a default pop-up for credentials, which looks different depending on browser, same as with javascript alert(), but I don't know how to display it. To know what I mean, go to http://fit.c2.com/wiki.cgi?WelcomeVisitors, there is a Login button at the bottom of the page, when you click it a pop-up appears. That is what I want to display. Any ideas?
