> Bracketed data binding to UI component do not works properly in FlexJS 0.8.0 nightly
build SDK. 
> *Works*
> {code}
> <js:Label id="lbl" text="{anyClass.fieldA}" width="300"/>
> {code}
> *Do not works*
> {code}
> <js:Label text="{anyClass.fieldB.fieldC}" width="300"/>
> {code}
> Binding to UI component seems do not works when there are multiple reference, i.e. _class.field.field_.
Following are the snippets of the codes which I used in this test:
> *InitialView MXML file*
> {code}
> [Bindable] private var anyClass:ClassA = new ClassA();
> protected function onTextInputChangeA(event:org.apache.flex.events.Event):void
> {
> 	anyClass.fieldA = myTI1.text;
> }
> 			
> protected function onTextInputChangeB(event:org.apache.flex.events.Event):void
> {
> 	anyClass.fieldB.fieldC = myTI2.text;
> }
> ...
> <js:VContainer width="500">
> 	...
> 	<js:TextInput id="myTI1" text="Change Value.." change="onTextInputChangeA(event)"/>
> 	<js:Label id="lbl" text="{anyClass.fieldA}" width="300"/>
> </js:VContainer>
> <js:VContainer width="500">
> 	...
> 	<js:TextInput id="myTI2" text="Change Value.." change="onTextInputChangeB(event)"/>
> 	<js:Label text="{anyClass.fieldB.fieldC}" width="300"/>
> </js:VContainer>
> {code}
> *ClassA*
> {code}
> public class ClassA extends EventDispatcher
> {
> 	[Bindable] public var fieldB:ClassB = new ClassB("Change Value..");
> 		
> 	public function ClassA() { }
> 	
> 	private var _fieldA:String = "Change Value..";
> 	[Bindable("fieldAChanged")]
> 	public function get fieldA():String
> 	{
> 		return _fieldA;
> 	}
> 		
> 	public function set fieldA(value:String):void
> 	{
> 		if (value != _fieldA)
> 		{
> 			_fieldA = value;
> 			dispatchEvent(new Event("fieldAChanged"));
> 		}
> 	}
> }
> {code}
> *ClassB*
> {code}
> [Bindable] public class ClassB extends EventDispatcher
> {
> 	public function ClassB(fieldC:String)
> 	{
> 		this.fieldC = fieldC;
> 	}
> 		
> 	private var _fieldC:String;
> 		
> 	[Bindable(event="fieldCChanged")]
> 	public function get fieldC():String
> 	{
> 		return _fieldC;
> 	}
> 		
> 	public function set fieldC(value:String):void
> 	{
> 		if (value != _fieldC)
> 		{
> 			_fieldC = value;
> 			dispatchEvent(new Event("fieldCChanged"));
> 		}
> 	}
> }
> {code}
> I've attached herewith the source to the test project. Please, take a look.
