TreeView filter
===

Well, Since I don't have the code here in this machine, I'm gonna try to be as clear as possible to explain what I have to do and hopefully get some help.
Well, I'm doing a remote pagination (using remoting) and to show the files I'm using a treeview, but first I developed this treeview to make easier my filtering job:
[PatternComposite][1]

Well, what I need to is, I have a comboBox with the extensions and when the user select between the values, the tree must be updated showing only the files with the selected(s) extension(s).

How can I do so ?

Thanks !
