Binding to functions is tricky. It doesn't know when its value changed. Binding to something that does is better. The function probably gets run at init time and errors which is eaten by Binding then never knows that the results came back. I would set selectedIndex in the results handler.

So I have an edit form which I have several combobox's that I can populate successfully from static arrays. So I want to duplicate this with results from an HTTPService. For some reason, the selectedIndex property does not run the function for selecting the data to be shown by default. The HTTPService gets launched at creationComplete when the user selects the edit component. I actually never get the trace in the findIndexAcct so that leads me to believe that it never gets executed. This is my code: <!-- COMBO BOX --> <mx:ComboBox id="acctComboBox" width="115" dataProvider="{getAcctListOnly.lastResult.customers.customer}" close="selectedItemAcct=ComboBox(event.target).selectedItem" openDuration="500" openEasingFunction="Bounce.easeOut" closeDuration="500" closeEasingFunction="Bounce.easeIn" selectedIndex="{findIndexAcct(data.acct)}" alternatingItemColors="[0xDFDFDF, 0xEEEEEE]" labelField="acct" cornerRadius="5"/> <!-- FUNCTION --> [Bindable] public var acctArray:ArrayCollection; private function getAcctListResultHandler(event:ResultEvent): void { acctArray = event.result.customers.customer as ArrayCollection; /* for (var i:int = 0; i < acctArray.length; i++) { trace(acctArray[i].acct); } */ } private function findIndexAcct(acct:String):int { var index:int = -1; for (var i:int = 0; i < acctArray.length; i++) { if ( acct == acctArray[i].acct) { index = i; } } trace(index); return index; }
