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.getInstance().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.
