I did as you suggested and I saw:

[('actbox_url', '%(content_url)s/RedirectingWorkflowAction?transition=release'), ('id', 'release'), ('__ac_local_roles__', {'dieter': ['Owner']}), ('actbox_name', 'Nachricht online stellen'), ('after_script_name', ''), ('guard', <Guard instance at 935b400>), ('script_name', 'release'), ('actbox_category', 'workflow'), ('title', 'freigeben'), ('trigger_type', 1), ('new_state_id', 'released')]

There is nothing obtained via acquisition.


Again: "obj.__dict__.items()" cannot use acquisition.
