The DG's selectedItem is bound to selectedSlide so anything that tickles it will reset the selectedItem. Maybe you want to call selectSlide(selectedSlide), or maybe you just want to init selectedItem once and not have it bound permanently?

I have a datagrid that should send it's selectItem value to a detail form. <mx:DataGrid selectedItem="{selectedSlide}" change="selectSlide(event.target.selectedItem as Slide)" dataProvider="{slides}" > Placing a breakpoint on the change property and observing the event.target.selectedItem value shows the event is carrying the expected info. But when execution reaches the handler: public var selectedSlide:Slide; private function selectSlide(pSlide:Slide):void { selectedSlide = pSlide ; // pSlide is now null. dispatchEvent(new Event(SELECT, true)); } the param is null. How do I go about figuring out where my error is? I reason that if there's something wrong with how I've typed 'Slide' I'd get a compile-time error. many thankx --steve...
