ComboBox binding is driving me crazy. [Bindable] public var selectedGranularity:String;
<mx:ComboBox id="granularityCombo" dataProvider="{source}" selectedIndex="{findSelectedIndex(this.selectedGranularity)}" labelFunction="labelFunction" /> If I set a breakpoint on selectedGranularity, it's setter is reached, but the findSelectedIndex function does not trigger. Any obvious mistakes?
