Justin Mclean updated FLEX-27648:
---------------------------------
Labels: easyfix easytest (was: )
> ViewStack.getItemIndex() throws error instead of returning -1 when item is
> not a child of the ViewStack
> -------------------------------------------------------------------------------------------------------
>
> Key: FLEX-27648
> URL: https://issues.apache.org/jira/browse/FLEX-27648
> Project: Apache Flex
> Issue Type: Bug
> Components: mx: View Stack
> Affects Versions: Adobe Flex SDK Previous
> Environment: Affected OS(s): Windows
> Affected OS(s): Windows
> Browser: Other (specify version)
> Language Found: English
> Reporter: Adobe JIRA
> Labels: easyfix, easytest
>
> Steps to reproduce:
> 1. create a ViewStack with no children and call getItemIndex()
> <fx:Script>
> <![CDATA[
> import mx.controls.Alert;
> protected function init(event:Event):void
> {
> try
> {
> event.target.getItemIndex(this);
> Alert.show("no error","ok");
> }
> catch (e:ArgumentError)
> {
> Alert.show(e.message,"a ha!");
> }
> }
> ]]
> >
> </fx:Script>
> <mx:ViewStack initialize="init(event)" />
>
> Actual Results:
> An ArguementError with message "Error #2025: The supplied DisplayObject must
> be a child of the caller." is thrown
>
>
> Expected Results:
> -1 should be returned as specified by mx.collections.IList.getItemIndex()
> "Returns int - The index of the item, or -1 if the item is not in the list. "
>
>
> Workaround (if any):
>
> A try/catch like above can be used as a work around but ideally this can be
> fixed directly in ViewStack so subclasses like TabNavigator are not affected.
> Proposed fix:
> public function getItemIndex(item:Object):int
> {
> if (contains(item as DisplayObject))
> {
> return getChildIndex(item as DisplayObject);
> }
> else
> {
> return -1;
> }
> }
>
