Depends on what your ContentController::editAction() does -- and since
that's not in the code snippet above, I can't really give you an answer.
All _forward() does is dispatch another action. It does nothing with the
database, and it doesn't clear any request parameters. My guess is that
editAction() is doing something that alters the table. Send that method,
and perhaps I can be of more help.
