Answer 1

I think the groups attribute has to have the module name included in the group name. For example, groups="base.group_extended" is used a lot. The module name should be from the module that originally created the group. It might also be that the groups attribute is not supported in tree views or on buttons, I don't know.

Can you post details of what your error says?
