Hi,
I'm currently looking into Workflow and Zope3. For some reason, I'm
running into the following, totally undescriptive error:
File "/home/ivo/Work/Zope3/Zope3-svn/src/zope/app/keyreference/persistent.py",
line 37, in __init__
IConnection(object).add(object)
File "/home/ivo/Work/Zope3/Zope3-svn/src/zope/interface/interface.py",
line 697, in __call__
adapter = self.__adapt__(obj)
File "/home/ivo/Work/Zope3/Zope3-svn/src/zope/interface/interface.py",
line 765, in __adapt__ adapter = hook(self, obj)
File "/home/ivo/Work/Zope3/Zope3-svn/src/zope/app/component/hooks.py",
line 95, in adapter_hook
return siteinfo.adapter_hook(interface, object, name, default)
File "/home/ivo/Work/Zope3/Zope3-svn/src/zope/interface/adapter.py",
line 406, in adapter_hook
adapter = factory(object)
File "/home/ivo/Work/Zope3/Zope3-svn/src/zope/app/keyreference/persistent.py",
line 65, in connectionOfPersistent
raise ValueError('Can not get connection of %r' % (ob,))
ValueError: Can not get connection of
<zope.app.workflow.stateful.instance.StatefulProcessInstance object at
0xb43a986c>
After some debugging I started debugging the following code:
def NewObjectProcessInstanceCreator(obj, event):
# used for: IProcessInstanceContainerAdaptable, IObjectCreatedEvent
pi_container = IProcessInstanceContainer(obj)
for (ignored, cwf) in zapi.getUtilitiesFor(IContentWorkflowsManager):
(.)
for pd_name in cwf.getProcessDefinitionNamesForObject(obj):
if pd_name in pi_container.keys():
continue
try:
pi = createProcessInstance(cwf, pd_name)
(zope/app/workflow/stateful/contentworkflow.py)
I'm not really sure what's happening here, but during my debugging
session, *inverting* the test seems alot more logical:
if pd_name not in pi_container.keys()
Doing this resolved my issue and I ended up with a working workflow.
This is not my code, I know nothing about it - does anyone know if my
fix makes any sense?
Cheers
Ivo
