#in the root of your CMF site create a folder with id, news
#
#select portal_workflow, see what workflow is being use for News Item

#goto the scripts tab
#create a Script(Python) with the id moveOnPublish
#parameters=state_change

#now goto the transitions tab and select the publish tranisition
#in the Script (After) select 'moveOnPublish'
#Save Changes

#finally we need to apply the new changes to items that
#use this workflow - this is not necessary but a good habit to form.
#click on portal_workflow and in the Workflow tab click the 
#Update Security Settings button. 


#--NOTE--
# I was having problems doing this when a Member didnt have access
# to the destination folder (where we are pasting objects)
# so to properly do this I had to create an External Method
# this is the external method and I just call it.
# the destination is a reference to the folderish object you want to
# paste the object.

# its really lame, you have set local roles on the object, then
# perform the paste/action and then remove the local roles.
# the upside is everything is transactional, the downside is
# manage_pasteObjects() is broken and should be fixed.
