collective.LockingWorkflow

This is a port of Raphael Ritz's LockingWorkflow product which only works on Plone 2.5x

Project Description

This is the original README.txt

Locking Workflow

What it does

 The locking workflow prevents concurrent editing in Plone.


Installation

 Like any other Plone product. Per default, the workflow is
applied to documents, events, and news items as specified in
the config file.

 A portlet is provided to indicate who has locked the current
item and since when. This portlet is inserted into the top
left slot (above the navigation box).

 If you are using it with a Plone version prior to 2.1, you should
first adjust the config file as explained in there.

How it works

 The locking workflow is a simple two state workflow (unlocked
and locked) restricting the edit permission in the locked state
to the newly introduced 'Editor' role.

 Per default, nobody has this editor role but it gets assigned
as local role to the current user as soon as (s)he invokes
the edit action which also triggers the 'lock' transitions
which takes the content item into the locked state. Saving
the edit form triggers the 'unlock' transition which takes
the content item back to the 'unlocked' state. The 'unlock'
transition can also be triggered TTW like any other workflow
transition.

 The locking workflow can be combined with any other workflow
as it exploits the fact that content types can be subject to
several workflows at once.


Caveats

 When adding the locking workflow to a type in ZMI make sure
that you also change the edit action of this type to invoke
'lock_and_edit', the form controller settings for the actions 
of 'lock_and_edit' and the form controller settings of the
method that invokes the view after successful editing (for
Archetypes that's 'validate_integrity'). If you add further
types in the locking workflow's config file instead, a simple
(re)install should take care of all of this.
