## Script (Python) "invokeTopic"
##bind container=container
##bind context=context
##bind namespace=
##bind script=script
##bind subpath=traverse_subpath
##parameters=REQUEST, RESPONSE, id, subj=None, title='', description='',
acquireCriteria='1'
##title=add a topic with 'id' and a string criteria value of 'subj' or 'id'
for 'Subject' programmatically
##
# instanate a topic with a id of 'id'
context.invokeFactory('Topic', id)

# get id of topic (thanks seb!)
obj=context[id]

# title and description of topic
obj.edit(acquireCriteria=acquireCriteria, 
         title=title, 
         description=description)

# add a string criteria for 'Subject'
obj.addCriteria(field='Subject', 
                criteria_type='String Criterion')

# set the value of the 'Subject' criteria
if subj is None: subj = id
crit=obj.getCriterion('crit__Subject')
crit.edit(value=subj)

# redirect to the topics page
RESPONSE.redirect(obj.absolute_url())
