Hi, i'm working with the how-to Serve PHP/Perl within Zope. I have an external python method called mymethod. In a zope-folder called "myfolder" i add the external method mymethod. I set the SiteRootPath to myfolder. I add i SiteAccess Rule to myfolder with the id of mymethod. This means on every REQUEST of myfolder/somewhere/somewhat the mymethod should be called and executed. Right ? Now the mymethod python file is that from the how-to and every time i open myfolder the error below comes up. Who can help me please. mfg as Traceback (innermost last): File /usr/share/zope/Zope-2.1.6-linux2-x86/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/share/zope/Zope-2.1.6-linux2-x86/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/share/zope/Zope-2.1.6-linux2-x86/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/share/zope/Zope-2.1.6-linux2-x86/lib/python/ZPublisher/Publish.py, line 169, in publish File /usr/share/zope/Zope-2.1.6-linux2-x86/lib/python/ZODB/Transaction.py, line 237, in commit File /usr/share/zope/Zope-2.1.6-linux2-x86/lib/python/ZODB/Connection.py, line 325, in commit (Info: (('OFS.Folder', 'Folder'), '\000\000\000\000\000\000\001~', '')) UnpickleableError: (see above)
