I am attempting to convert some stuff running correctly on Zope 2.6 to 2.7 under Win2000. I have a "product" that I created by following the instructions for creating products in the "PythonScripts" product to allow access to the Python DSV module from http://python-dsv.sourceforge.net/. This seems to function correctly under 2.6 but under 2.7 the DSV.py module apparently fails to convert to byte code ( my understanding is this is done on Zope startup when required) thereby making the "product" non functional. I am not exactly sure why this fails though. Any idea how I can approach this problem? How can I get more information on this apparent failure?
