I have a custom actionscript object defined as bindable with a number of public properties.

but no luck with that either. I'm probably missing something simple here, but not sure what it is.

The labels text will be "Property", but if object.property is changed, the label isn't updated. Is there any way around this?
I am having a table at the backend, so when a query is asked at the frontend for an object, all the tabs in the front end should be populated with the details of the query object. I am able to pick the query object at the back end , but i dont know how to bind that object across all the tabs in flex. I am getting an error type coercion failed, cannot convert X to mx:Array collection

Does there exist a Flex view component that you could just pass it a custom object with all public fields/properties that it could reflect over and produce a basic UI view using flex components. Is it possible to use something like the Spark DataGrid with one item laid out vertically. It would only have to support:

Can't seem to bind to data from within a custom component. I've tried BindUtilis and {} but can't seem to fathom it out. Here's what I've got:
I have a class DataModel which has been made bindable
Within Mainn.mxml I have two components: DataGrid (used for testing) & CustomComponent (which extends Canvas)
When the data within DataModel.somelist is updated the DataGrid reflects the changes but the CustomComponent doesn't appear to.
I was expecting to see the trace (CustomComponent.dataProvider) fired whenever this._dataModel.itemList is changed. [code]...
For the application that I am developing in AIR, I have removed the chrome through the app.xml. I am managing the features of minimizing, maximizing, close, resize and all other functions from within the application. I am facing a problem with resize feature. I have defined the grips for resizing and also I am able to display my custom cursor when mouse moves over it. The problem is that only the part of this cursor is visible which lies inside the boundary of the application rest of the cursor image is hidden.For implementing the custom cursor, I do the following.Embed the cursor image.
[Embed(source='/resources/images/resize_right.png')]
public var resizeRight:Class;
Add the event listener to the canvas that acts as a grip.
rightResizeGrip.addEventListener(MouseEvent.MOUSE_OVER, function(e)
{
setResizeCursor(CURSOR_RIGHT);

I'm creating a custom component (based on ComboBox) and overriding some base methods. Recently I've found it acts weird when I set it's width in percents, rather than a fixed width. It tends to continuously call the commitProperties method and fail in the end. When I set it's width to fixed value - all works like a charm. What am I missing to implement? Here's some code ..
override protected function commitProperties():void {
super.commitProperties();

I have a need to validate a field against our database to verify unique-ness. The problem I seem to be having is that the validators doValidation() exits before we've heard back from database.
How can I have the validator wait to return its payload until after we've heard from the DB?
Or perhaps a better question might be (since I think the first question is impossible), how can I set this up differently, so that I don't need to wait, or so that the wait doesn't cause the validation to automaticallly return valid?
I'm in a Flex Mobile application project. I need to dispatch an event to the lexGlobals.topLevelApplication and it has to contain a custom message. I'm trying to make an object and dispatch it like this:

receivedObjMsg.name = "receivedMessage";

I have a simple object defined by an object literal, and have a couple functions assigned to this object. Inside the functions, I try to access global variables, and it only gets undefined. The Flex debugger tells me the variables are just right up the scope tree.Yes, I know I can access Thing by using 'this', that doesn't solve my scope issue though.Project Flex Compiler Settings: Flex SDK 3.4, Require Flash Player 10.x.Example:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="Thing.bling();">

but how to add the id attribute as the 'data' field of the dropdown so when an item is selected, it returns that field?
Because I want to avoid repetive code, and I'm using a lot of text formats, I created a CustomTextFormat class in Flex Builder.
Another class, called CustomInputBox.as is using this object to create a format:

I am using Flex 4 and for whatever reason I cannot get the following code to work which happens inside of a ListEvent handler for a dataGrid:
_tempRule = DataGrid(event.currentTarget).selectedItem as Rule;
Rule is a custom class, and the above code always returns null. The dataprovider for the datagrid is an ArrayCollection. If I try to wrap the above code to make it like the following:
DataGrid(event.currentTarget).selectedItem as Rule
I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert Object@e15a971 to com.mycompany.arcc.business.Rule
Now I know I have done this before with native Flex classes like Button, etc, but it my case it will not work. Here is the Rule class:

I have a Flex tree control that holds a tree full of various types of objects. I'd like to change the label of the item based on this type (and other properties). I'd prefer to do this in a custom TreeItemRenderer rather than via label or labelfunction.It seems that whatever I do, I cannot typecheck nor cast the objects and thus I get [Object object] in the nodes of my tree. Here is my renderer:
public class MyCustomTreeItemRenderer extends TreeItemRenderer {
// Overriding to set the text for each tree node.
override protected function updateDisplayList(unscaledWidth:Number,

I am thinking of writing a subclass of ArrayCollection, similar to ClearToolkit's that can be smart about managing my remote objects when coming back from BlazeDS.I am wondering if it is possible to get Flex to put my collection of objects in my own custom collection instead of defaulting to ArrayCollection? If not, I'll need to pull everything out of the collection it comes in in order to populate my own.

View 3 RepliesThis is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent.
dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
This is my custome event

When the XMLListCollection is updated in the DataGrid, I want it to add the XML (bind it) into the Model. How would I do this? Or if not possible, how would I manually add XML into the Model?
This is a rough example of what I'm trying to do. Adding data to the DataGrid works fine; it just doesn't go into the Model when sending to the HTTPService.
<mx:Model id="model">
<root><colors>{collection}</colors></root>
</mx:Model>

If you once run an ObjectBuilder the object instantiated will be cached and next time you use an PropertyInjector or something else, the instantiated object will be used instead of creating a new object. Or at least this should be like this :) But in the example below it seems that mate tries to instantiate the object again: The following error occurs:

I've developed a component which is a combination of a few items (canvas, labels, etc...) but when I try to bind it to a variable such as: {stationXML.getItemAt(1).AAA.@value}, it doesnt work. Before I combined all the items in a component, they were all in the main MXML file at which time they worked. Not sure if it matters, but the "stationXML" arraycollection variable is declared inside the file "Station.as".
