This patch allows to update all objects that are using one single workflow,

for example after the permissions per state for this workflow were modified,
instead of using the portal-wide updateRoleMappings method, which might
generate a much bigger transaction.

 # This patch allows to use workflowmethod as an after_script
 # However, the right way of doing would be to have a combined state of TRIGGER_USER_ACTION and TRIGGER_WORKFLOW_METHOD
 # as well as workflow inheritance. This way, different user actions and dialogs can be specified easliy
