paul j3 added the comment: In
_ActionsContainer._add_container_actions there is this note: # add container's mutually exclusive groups # NOTE: if add_mutually_exclusive_group ever gains title= and # description= then this code will need to be expanded as above In other bug/issues we've noted that the way to give an exclusive group a title and description is to nest it in an argument_group. So it looks like no one has worked through the details - in this parent situation - of adding a nested mutually exclusive group. In my preliminary tests, it looks like the 'group_map' is being messed up by the block of code that adds the mutually_exclusive_groups. I don't know how easy it is to fix that. The immediate user solution is not use parents and nested mutually exclusive groups together. ---------- nosy: +paul.j3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25882> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
