[Zope-CMF] How do I get the action for 'folderContents'?

[Grégoire Weber]

Hi Tres,
hi all,

to be sure not to run into problems caused by actions without a 'id' 
(e.g. workflow actions) the following corrected code should be used. 
I replaced x['id'] by x.get('id', None).

<CODE>
# workaround: get the absolute action path of an action not registered by an 
# object in the portal_types tool like the 'folderContents' action:
actions_list = []
for actions in
context.portal_actions.listFilteredActionsFor(context).values():
    actions_list.extend(actions)
action_path = filter(lambda x:x.get('id', None) == 'folderContents',
actions_list)[0]['url']
</CODE>

Greetings, Greg
