I have a primitive example that demonstrates somewhat what I am looking
for. This works crudely. The comboBox blinks very obviously with every
key stroke, I presume because of the refresh(). It would also be nice
if the default selection was the first item in the dataProvider, but
with the ability to override this with a new value if necessary.
[Bindable]
private var comboFilterStr:String = new String();
....
private function comboFilter(o:Object):Boolean
{
return comboFilterStr.toUpperCase() ==
o.substr(0,comboFilterStr.length).toUpperCase() ;
}
private function test(ctrl:ComboBox):void
{
comboFilterStr = ctrl.text;
ctrl.dataProvider.filterFunction = comboFilter;
ctrl.dataProvider.refresh();
ctrl.open();
}
....
<mx:ComboBox
id="te_application" change="test(te_application)"
prompt="Select Application"
width="100%"
rowCount="5"
dataProvider="{applicationsAry}"
editable="true"/>
