Yes, you are right. This would be cool. I think that need more optimzation and functionality. It's a midnight version of it. :-)
I found some blog's saying that the comboBox or any other UI based on listRendering need this kind of behaviour, I think that they need To. So here come the changes. Can I detect if the dataProvider of the combo change.? I suppose yes. It's a good idea to map the dataProvider.? Map the object will do more faster the task of select an item. I will play a litle more with it.
