It works fine except for one point : I'd like node attributes to be hidden to the en user. The only purpose of that dialog would be to select a Node (so i guess i should set Mode.SelectElementType to "Node" ). I don't want to show unnecessary information to the end user that would make it more difficult to understand.
As of right now I don't know how to do this and the user can still double-click on a Node a it would show him a list of it's attributes. How can I restrict that?
