Hi,
Instead of this use
BindingUitls. bindProperty( this,"xyz" ,MyModel, getInstance( ).someVar) ;
This statement is called in the creationComplete of the component.
Cheers it will work..

Subject: Re: [flexcoders] [Bindable] is not getting updated..
Josh,
Is it a right way to do the following:
[Bindable] private var xyz:String = MyModel.getInstance ().someVar;
Now, if I use xyz in my code then it is not updated. Where as if i use
'MyModel.getInstanc e().someVar' then I am getting perfect result.
For Ex:
<mx:Label text="{xyz}" /> // view not updated with changes in model.
<mx:Label text="{MyModel. getInstance( ).someVar} "/> //view updated everytime
with changes in model..
So, I didn't get the difference between two above logically.
Please explain the case as above. Thanks.
