I do not use binding to change dataProvider property values. Rather, I use an e4x expression to locate the desired node(s), then directly set the property values I want.

I have a MenuBar where the dataProvider is specified in MXML as an XMLList. For the "enabled" attributes I do something like: enabled="{allowThis()}" However, to get databinding working I end up passing in the relevant bindable property and then ignore it within the implementation of allowMe(). For example: enabled="{allowThat(myBindableVar)}" This works, but IMHO is horrible because it requires either messing up my API or creating a load of functions like: function allowThat(myBindableVar:Object):Boolean { allowThis(); } Is there another approach? A standard approach? As another workaround, maybe there is a way to recalculate the enabled flags for the whole MenuBar? Maybe resetting the dataProvider? -- View this message in context: http://www.nabble.com/Best-practice-for-databinding-with-MenuBar--tp2062 2610p20622610.html <http://www.nabble.com/Best-practice-for-databinding-with-MenuBar--tp206 22610p20622610.html> Sent from the FlexCoders mailing list archive at Nabble.com.
