Hi folks I'm attempting to use Plone with CMF 1.4.2 and Zope 2.7b2. I'm getting errors in PloneFolder.__call__() where I first substituted the call to the local (PloneFolder) _getViewFor() with that of the one in CMFCore.utils (since in its original state, the local _getViewFor() failed because it thought action was a dict). This fails because CMFCore.utils._getViewFor() returns the original PloneFolder object - which gets __call__()ed again until we run out of stack. I also see this behaviour with my own custom folder class. I then tried fixing the PloneFolder._getViewFor() so it treated action as an object. This function now fails in the call to restrictedTraverse(action.action) where the incoming path is expected to be a list or string, not an action object. Being something of a newcomer to CMF, Plone et al, I have to say I'm a bit stuck at the moment. Do I have to roll back to earlier versions of CMF/Plone/Zope, or is there a quick fix? What would be _really_ handy is if some knowledgeable individual could offer a brief explanation of the purpose of _getViewFor(). I'm kind of enjoying poking around in all this code, but its taking way longer than I budgeted. Any info gratefully received. Thanks Mark
