Using Zope 2.3.1, I installed a product MSWordDocument from zope.org/Products--transparent conversion to HTML of any MSWord.doc. Once installed, I can add an instance of the product through the *local_host/manage* screen. Is there a way to extend this product that I can use it in my CMF portal? I have read the following How-To: Minimal Zope programming How-to *maxm Minimal Zope programming How-to - The Sequel *maxm PortalPoll *DaveW Taming The Wild Types Tool *Tres Seaver Scriptable Type Information *Tres Seaver But with no succesful results. Has anyone succesfully created a portal_type to use with this product? trace--- Traceback (innermost last): File /home/djones/Zope-2.3.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /home/djones/Zope-2.3.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/djones/Zope-2.3.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 171, in publish File /home/djones/Zope-2.3.1-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: invokeFactory) File /home/djones/Zope-2.3.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: invokeFactory) File /home/djones/Zope-2.3.1-linux2-x86/lib/python/Products/CMFCore/PortalFolder. py, line 368, in invokeFactory (Object: Traversable) File /home/djones/Zope-2.3.1-linux2-x86/lib/python/Products/CMFCore/TypesTool.py, line 714, in constructContent (Object: Traversable) File /home/djones/Zope-2.3.1-linux2-x86/lib/python/Products/CMFCore/TypesTool.py, line 471, in constructInstance (Object: ElementWithAttributes)
