all right, i am not an expert but i think you are going to need to extend the
ButtonBar, override the createNav and create it so it looks for that variable
and acts accordingly. the labels in the button bars are objects so u can
disable them. sorry

Subject: Re: [flexcoders] Bind 'enabled' properties of ButtonBar to model
I think I am missing something... not sure why this helps me to
pass it as 'data' instead of 'enabled'. I still can't find a what to bind it
automatically so that the change in the model with update the ButtonBar.
Here is a sample app. Possibly you can show me what I am doing wrong. Thanks!

if u do this instead that works ({label:button1, data:false} ,{label:button2,
data:true} ) and then u can scan the data to see if u need to enable or not

Subject: [flexcoders] Bind 'enabled' properties of ButtonBar to model
To expand on a previous post, I am trying to find a elegant way to do
this: (I am thinking there must be a simple solution to this.)
I have a Button bar who's DataProvider is bound to an ArrayCollection
of objects on the model:
({label:button1, enabled:false} ,{label:button2, enabled:true} )
Since the ButtonBar doesn't not read the 'enabled' property by
default, I would like to bind the 'enabled' property of each button
to this data provider as well so that making an update to the
DataProvider will toggle the enabled/disabled of individual buttons
based on the users interaction in the application. Unfortunately, I
can't seem to find a way get this binding to work so that all I need
to do is update the enabled property in each object on the model.
Thanks for the help.
