I've used code like this in the past
var myParent:*=owner
while (myParent.className!='ComboBox'){
//pretty much everything will have either a parent or an owner
if (!(myParent.owner==null)){
myParent=myParent.owner;
}else{
myParent=myParent.parent;
}
}
//myParent is a ComboBox if you get to this point
Note that you need to be REALLY sure this will eventually hit a
ComboBox, or it will result in an endless loop. You can add in a
loop counter for safety, and exit after, say, 100 loops in case of a
failure to find a combobox.
Possibly you could also extend ComboBox to listen to SystemManager
and redispatch events.

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.

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.
[Event(name="customSelect",
type="myevents.CustomEvent")]

OK, that works, thank you very much for your help. IMO, seems like an
awful lot of work to achieve this behavior, though.

Cast owner to something like ListBase to get round the compiler error.

OK, I tried this but I get a compiler error - owner (which is a
