[jrief]

In django-cms reversion has been replaced by djangocms-history.
Therefore Cascade shall adopt to this change.

With this PR #281 it works in part, because with the plugins who have multiple pk in their description that's there is this error:

otherwise the other plugins works well with undo and redo.

By changing the line of djangocms_history/models.py#L403:
if data and 'pk' in data:
to
if data and 'pk' in data and 'model' not in data:

With this change and this PR #281, djangocms-cascade plugins work with djangocms-history.

Many thank to @haricot for changing this. Unfortunately I had no time to fix this. Will check that PR soon.

djangocms-history and djangocms-transfer works since the commit d7e4d4c
if it suits you this may be closed.
