Do a search of the archives. It's HierachicalData that's the problem, it eats the refresh events from the dp. Your search should turn up the code posted for the solution.

But I'm having trouble firing the refresh at the right time. In my application, an event is fired when a navigation choice is made. The event switches the view, causing instantiation of the component which contains the ADG. The event also initiates a service call to retrieve data, which is then injected into an ArrayCollection in the view component with the ADG. I realize that the instantiation of the view and ADG may (or may not) take place before the data is returned. So I have done two things: in my ADG, I have placed a "refresh" of the GroupingCollection in the "initialize" action of the ADG (as recommended in the docs). I have also placed an eventListener on the ArrayCollection which is the dataprovider, listening for a COLLECTION_CHANGE event. Here's some code: ================= [Bindable] public var acJobsInProgress:ArrayCollection = new ArrayCollection; private function init():void{ acJobsInProgress.addEventListener(CollectionEvent.COLLECTION_CHANGE,grid Refresh); } private function gridRefresh(e:Event):void{ divGrouping.refresh(); } ================= The gridRefresh function executes when the ADG is initialized, but the underlying AC is empty -- not unexpected. But the function is never fired again. I've set further breakpoints, and I can see that the AC is being correctly populated from the service. But the GroupingCollection is not refreshed. I would expect that the COLLECTION_CHANGE listener would fire when the AC is populated from the service. But it doesn't seem to. Can someone please help me understand where I'm going wrong? -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com <http://www.mediumcool.com> 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560
