traceback while creating agreement

[pjstevns]

Kaspars,

I'm getting:

File "/usr/lib/python2.5/site-packages/openerp-server/addons/account_invoicing/invoicing.py", line 1504, in _prolong
self.pool.get('ir.cron').write(cr, uid, obj.cron_id.id, {'numbercall':cron['numbercall']+numbercall+1,'active':True})
File "/usr/lib/python2.5/site-packages/openerp-server/addons/base/ir/ir_cron.py", line 133, in write
self._poolJobs(cr.dbname)
File "/usr/lib/python2.5/site-packages/openerp-server/addons/base/ir/ir_cron.py", line 107, in _poolJobs
cr.commit()
UnboundLocalError: local variable 'cr' referenced before assignment

any ideas?? I'm guessing the _prolong call shouldn't be used to begin with, but rather _prolong_optimized, but perhaps you can shed some light here.

Paul.
