OK, I tried this but I get a compiler error - owner (which is a DisplayObjectContainer) doesn't have a property owner.

OK, that works, thank you very much for your help.

Re: [flexcoders] Re: ComboBox ItemRenderer Custom Events only go to SystemManager - WHY?????
Just as a precaution here, this owner parent stuff shouldn't be necessary, you should be picking up the event flow, just to check have you (a) set bubbles to true and (b) ensured if your using an mxml component you've assigned the appropriate metadata tag for your custom event in the ComboBox component i.e. mx:Metadata[Event(name=customSelect, type=myevents.CustomEvent)]/mx:Metadata Cheers, Simon newtriks.com On 9 Jul 2008, at 19:30, Battershall, Jeff wrote: OK, I tried this but I get a compiler error - owner (which is a DisplayObjectContainer) doesn't have a property owner.

RE: [flexcoders] Re: ComboBox ItemRenderer Custom Events only go to SystemManager - WHY?????
Simon, I had done as you have described and I agree that it should be that simple, but the fact that a ComboBox is using PopUpManager to show it's list appears to be the issue. Firing the event from my custom itemRenderer doesn't seem to get noticed by the ComboBox. Of course there's always the possibility I'm not doing something correctly, but to my knowledge, what you decribe SHOULD work. I don't partcularly care for this ListBase(owner).owner stuff but it does have the virtue of working.
