Hi, I encountered an error using the SetEventHandler and made a simple test case to see what was the problem: In my app I have a component that contains button and dispatches a "goPrevious" event when the component::button is clicked. Following the "goPrevious" event, the main app changes its state. The new state uses the SetEventHandler to change the "goPreviousHandler":
My main app: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:local="*" creationComplete="init()"> <mx:Script> <![CDATA[ import mx.controls.Alert; private function init():void { trace(document.toString()); } private function onClick1(evt:Event):void { Alert.show("chnaging from state 1 to state 2"); currentState = "myState" } private function onClick2(evt:Event):void { Alert.show("state 2"); } ]]> </mx:Script> <mx:states> <mx:State name="myState"> <mx:SetProperty target="{bt}" name="alpha" value="0.2" / <!--<mx:SetEventHandler target="{bt}" handlerFunction="onClick2" name="goPrevious" /> --> </mx:State> </mx:states> <local:MyButton id="bt" goPrevious="onClick1(event)" /> <!--<mx:Button id="bt" click="onClick1()" /> --> </mx:Application> --------------------------------------------------------------- The Component: <?xml version="1.0" encoding="utf-8"?> <mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" width="100" height="100" click="onClick()" creationPolicy="auto" > <mx:Metadata> [Event(name="goPrevious", type="events.NavigationEvent")] </mx:Metadata> <mx:Script> <![CDATA[ import events.NavigationEvent; private function onClick():void { dispatchEvent(new NavigationEvent(NavigationEvent.GO_PREVIOUS)); } ]]> </mx:Script> <mx:Button label="previous" click="onClick()" /> </mx:VBox> And this is the error you get from the SetEventH/handler object: ReferenceError: Error #1069: Property __bt_goPrevious not found on MyButton and there is no default value. at mx.states::SetEventHandler/apply() It seems that inside the SetEventHandler.apply() function it can't find the oldHandlerFunction. I'm struggling this bug for hours now and been goggling it a lot, yet nothing useful was found... I'd be grateful if anyone take a look at that. Thanks in advance, Almog Kurtser
