BindingUtils will automatically notify "this" object about Property change
event.
Make sure xyz is bindable.
Example look below:
BindingUtils.bindProperty(textBox,"text",grpCbx.selectedItem,"value");
Here my textBox ix TextInput control and grpCbx is Combo Box . I used this
statement in creation complete
So whenever my combo box selected item changes , it automatically binds into
the TextInput Control.
Let me know your view and also if possible paste some part of the code.
Thanks,

Subject: Re: [flexcoders] [Bindable] is not getting updated...
Do I explicitly need to dispatch any event for BindUtils.bindPrope rty(..) to
happen ??
Cuz, I am not getting my "xyz" var changed with the change in someVar.
Note: I am putting this line of code
(BindingUtils. bindProperty( this,"xyz" ,MyModel. getInstance, "someVar" ) in
creationComplete( ).
Thanks,
Manu.
