Problem with Navigator [message #335435]

Hi,

I've got a problem in my navigator. I'd like to make the Undo action work
even if I don't have an element selected but the Navigator Action Service is
prepared to work only when something is selected. I've thought of
subclassing NavigatorActionService but I don't know which extension point I
can use to specify that I prefer to use my subclass rather than
NavigatorActionService. Does anyone know which extension point allow me to
do that? ...or any other solution to my problem??

Thanks in advance

Mario

Instead of using the CNF actionProviders, I would consider the use of
commands instead. They are easier to use and give you much more
flexibility.

This will get you started:

You can simply add your command to the popup menu associated with your
navigator under whatever conditions you like.

I think you can use the UndoActionHandler to actually run the undo.

HTH,

Francis
