problem when changing method signature of pushed-in method

I have some pushed-in "list" and"show" methods, to which I add "Authentication auth" to the method signature. The problem is that Roo re-generates my pushed-in methods since my method has a different signature than the original list or show method. This creates a conflict in the controller mappings (essentially it creates a duplicate method mapped to /events GET).

See discussion.

Stefan proposed adding list and show options in @RooWebScaffold (which already provides ability to turn off create, update, delete). Not sure this is ideal as it would turn off Roo management of jsps.
