[flexcoders] ComboBox binding

[Richard Rodseth]

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?
