Refresh() is intended to re-apply a sort of filter to a collection. If it is working in your case it is a side effect.
I couldn't find your previous post to look at the code, but I still suspect recycling issues. For a combo box, you have to do two actions on set data (actually in commitProperties, of course). You must re-assign to dataProvider, and you must set the selectedIndex (you can only use selectedItem if your items are simple strings or numbers). Are you doing both of those things? I have an example on cflex. It is more complex than necessary because I wanted it to be generic: http://www.cflex.net/showFileDetails.cfm?ObjectID=767 Tracy Spratt, Lariat Services, development services available _____ From: [email protected] [mailto:[email protected]] On Behalf Of Laurence Sent: Saturday, February 06, 2010 4:29 AM To: [email protected] Subject: [SPAM] [flexcoders] Re: Custom ItemRenderer still not working... Well, I found a work-around... I added the following code inside my ComboBox ItemRenderer: override protected function focusInHandler(event:FocusEvent):void { listOfFees.refresh(); } For some reason, with this in there, you have to double-click on the combo box to open it, but the drop-down shows the correct data 100% of the time. Good enough for now. --- In flexcod...@yahoogro <mailto:flexcoders%40yahoogroups.com> ups.com, "Laurence" <lmacne...@...> wrote: > > Well, I installed FlashBuilder 4 Premium Beta 2, imported the project into there, and ran the code. > > It is EXACTLY THE SAME in FB3 and FB4 -- the exact same problem appears. I scroll down in the DataGrid, and the numbers in the ItemRenderer's drop down change (but not the selected number being displayed.) If I select one of the incorrect numbers, the drop-down immedately changes to the correct numbers, and the number I would've selected (had it been displayed correctly) shows as the selected item in the combo box.
