""" req = REQUEST self.id = id self.title = title self.users = (req.has_key('users') and req.users or '') self.emails = (req.has_key('emails') and req.emails or '') self.formular = (req.has_key('formular') and req.formular or '') The last line occures the error: ErrorType: UnpickleableError ErrorValue: Cannot pickle <type 'Python Method'> objects Traceback (innermost last): File /home/xfintra/xiteflex130/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /home/xfintra/xiteflex130/lib/python/ZPublisher/Publish.py, line 114, in publish File /home/xfintra/xiteflex130/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: xiteflexWorkflowEngine) File /home/xfintra/xiteflex130/lib/python/ZPublisher/Publish.py, line 102, in publish File /home/xfintra/xiteflex130/lib/python/Zope/__init__.py, line 173, in commit File /home/xfintra/xiteflex130/lib/python/ZODB/Transaction.py, line 234, in commit File /home/xfintra/xiteflex130/lib/python/ZODB/Connection.py, line 346, in commit (Info: (('Products.xiteflexWorkflowEngine.xiteflexWorkflowAction', 'xiteflexWorkflowAction'), '\x00\x00\x00\x00\x00<\xf3\x91', '')) UnpickleableError: (see above) If i write.. self.formular = '' ..everything works fine. I also tried this: if req.has_key('formular') and req.formular: self.formular = req.formular else: self.formular = '' Same result: "UnpickleableError" The value of req.formular is ''! Has anybody an idea? Normaly this should work, or not? Thanks for your help. Regards woolfy
