[Zope3-Users] ForbiddenAttribute problem with viewlet manager and hurry.workflow

[Thierry Florac]

  Hi,

I'm trying to use the "hurry.workflow" package (loaded from CVS) to
handle a simple workflow.
I've created a ViewletManager to display available transitions, but a
ForbiddenAttribute exception is raised. I know that this exception is
due to missing permissions settings, but no configuration is working...

This is the code of my viewlet manager :

class WorkflowTransitions(object):

implements(IContentProvider)
adapts(Interface, IDefaultBrowserLayer, Interface)

template = ViewPageTemplateFile('transitions.pt')

def __init__(self, context, request, view):
self.context = context
self.request = request
self.__parent__ = view

def update(self):
wf = zapi.queryUtility(IWorkflow)
if wf is not None:
info = IWorkflowInfo(self.context)
self._transitions = info.getManualTransitionsIds()
else:
self._transitions = []

@property
def transitions(self):
return self._transitions

def render(self, *args, **kw):
return self.template(self, *args, **kw)

I've tryed to define several security declarations in ZCML, but none is
working. The exception is raised while accessing
"getManualTransitionIds()" method :

  File ".../onf/publication/browser/viewlets/transition/__init__.py", \
  line 45, in update
ids = info.getManualTransitionsIds()
  ForbiddenAttribute: ('getManualTransitionsIds', \
  )

I've also tried to use a simple content provider with an adapter but got
the same result.

Thanks for any help,

  Thierry Florac

Oops, Sorry !!
The error was a simple syntax error : correct method name is
"getManualTransitionIds()", without the "s".
But as said in a previous post, the ForbiddenAttribute exception is
strange in such a case...

Thanks,

See my other post on manually making registrations. Also 
the "hurry.workflow"'s configure.zcml file does not contain much. You 
certainly will have to add some more yourself. It looks like hurry.workflow 
will need some TLC (Tender, Love, and Care) to work nicely again.
