I don't know why it's behaving like that, but it seems to work if you set the state after the form item has been created, like this:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";> <mx:Form> <mx:FormItem label="Type" creationComplete="st.currentState='taskQueue'"> <view:SectionTypeControl id="st" /> </mx:FormItem> </mx:Form> </mx:Application> Anyone has an explanation?
