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

2006-10-18 Thread 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', \
  hurry.workflow.workflow.WorkflowInfo object at 0xb4f5cd8c)

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,
