Remove an item from autocomplete combobox after add that item to jlist in java

Question

From what I can see from your description and code you're simply using the GlazedLists convenience methods to set up the initial auto-complete component, yet you're not using the fundamental part of GlazedLists to stitch the various elements together: EventLists.

Sure - you have derived a one off EventList to populate the autocomplete installation, but GlazedLists really expects you to be utilising EventLists to hold your objects throughout and not during a quick interchange. Pure Java Swing components like JComboBox and JList force you down the route of arrays and vectors, but GlazedLists provides a lot of helper classes if you stick to the various EventList implementations as your fundamental collection class. It has classes for combobox and jlist models, and selection model classes and these conveniently link up the EventLists and Swing components and you can really simplify your code once you go down this route.

Here's a very crude example of what I think you're trying to achieve. I think the code speaks for itself rather than me rambling on any longer. Note: I used GlazedLists 1.8.
