Many actions in the editor cannot be correctly undone. Using the ctrl+z shortcut often leaves the editor and model in conflicting states. I believe the root cause of this is that the dependence on databinding and a specific model type is confusing things. What's more, the specific model class being used is extended from teh wizard model. This seems completely inappropriate, because the server editor is really just backed by the server working copy, and doesn't need 80% of the fields that are in the wizard model.

Also, since a good many actions like changing the connection or the source project, make no sense and almost never function correctly, many of these actions should really not be available. They only make it more likely for a user to break his environment.
