I have updated the example to include the same trace statements after the moveNext() call. This provides the expected result. It seems that the bookmark must update at some point later, although this doesn't explain the change watcher on the bookmark it's self!
The output from the following is: currentE, current=Mark currentE, bookmark=Bobby currentE, index=0 bookmarkE, current=Mark bookmarkE, bookmark=Bobby bookmarkE, index=0 Event, current=Mark Event, bookmark=Bobby Event, index=0 Event, index=0 AfterMove, current=Mark AfterMove, bookmark=Mark AfterMove, index=1 They should all read Mark... <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute" backgroundColor="#333333" creationComplete="onCreationComplete()" width="100%" height="100%" viewSourceURL="srcview/index.html"> <mx:Script> <![CDATA[ import mx.events.PropertyChangeEvent; import mx.events.FlexEvent; import mx.collections.ArrayCollection; import mx.collections.IViewCursor; import mx.collections.ICollectionView; import mx.binding.utils.ChangeWatcher; import mx.controls.Alert; [Bindable] public var myArrayCollection:ICollectionView = new ArrayCollection([ "Bobby", "Mark", "Trevor", "Jacey", "Tyler" ]); [Bindable] public var cursor:IViewCursor = myArrayCollection.createCursor(); public function onCreationComplete():void { ChangeWatcher.watch( cursor , ["current"] , test , true); ChangeWatcher.watch( cursor , ["bookmark","value"] , test2 , true); cursor.addEventListener( FlexEvent.CURSOR_UPDATE, test3); } public function test( e:FlexEvent ):void { // Triggered when the current property of the cursor changes trace('currentE, current='+cursor.current); trace('currentE, bookmark='+cursor.bookmark.value); trace('currentE, index='+cursor.bookmark.getViewIndex()); } public function test2( e:FlexEvent ):void { // Triggered when the bookmark property of the cursor changes trace('bookmarkE, current='+cursor.current); trace('bookmarkE, bookmark='+cursor.bookmark.value); trace('bookmarkE, index='+cursor.bookmark.getViewIndex()); } public function test3( e:Event ):void { // Triggered when the cursor dispatches a cursor update event trace('Event, current='+cursor.current); trace('Event, bookmark='+cursor.bookmark.value); trace('Event, index='+cursor.bookmark.getViewIndex()); trace('Event, index='+cursor.bookmark.getViewIndex()); } private function _onClick():void { cursor.moveNext(); trace('AfterMove, current='+cursor.current); trace('AfterMove, bookmark='+cursor.bookmark.value); trace('AfterMove, index='+cursor.bookmark.getViewIndex()); } ]]> </mx:Script> <mx:Button label="Move Cursor" click="_onClick()" themeColor="#FAFAFA" color="#FFFFFF" horizontalCenter="0" verticalCenter="20"/> </mx:Application>
