Ok, some progress. If I define the binding in ActionScript before adding it to
its parent container, it works halfway; meaning the second binding works, but
not the first one. It's not 2-way.
Here's the updated AS code:
var innerHBox:HBox = new HBox();
var dtc_acm:AutoCompleteModified = new AutoCompleteModified();
dtc_acm.dataProvider = data2;
dtc_acm.labelField = 'id';
BindingUtils.bindProperty( dtc_acm,'selectedIndex',cp_acm,'selectedIndex' );
var cp_acm:AutoCompleteModified = new AutoCompleteModified();
cp_acm.dataProvider = data2;
cp_acm.labelField = 'name';cp_acm.width = this.CP1.width;
BindingUtils.bindProperty( cp_acm,'selectedItem',dtc_acm,'selectedItem' );
innerHBox.addChild( dtc_acm );
innerHBox.addChild( cp_acm );
Why did the position of the code matter? Why is it only 1-way binding? Still a
little confused as to these things.
Thanks for listening,
Matt
