Hi, im using zope 2.4.1. I tried the small "underscore modification" and the External Method. Both did not work! Using the External Method creates the following error: ---- Error Type: AttributeError Error Value: expandtabs [...] File /usr/lib/Zope-2.4.1-linux2-x86/lib/python/Products/ExternalMethod/ExternalMethod.py, line 274, in __call__ (Object: stx_to_html) (Info: ((<DTMLDocument instance at 879ee40>,), {}, (1,))) File /usr/lib/Zope-2.4.1-linux2-x86/Extensions/stx_to_html.py, line 109, in stx_to_html (Object: test) File /usr/lib/Zope-2.4.1-linux2-x86/lib/python/StructuredText/ST.py, line 113, in StructuredText (Object: test) File /usr/lib/Zope-2.4.1-linux2-x86/lib/python2.1/string.py, line 295, in expandtabs (Object: test) AttributeError: (see above) ---- Any suggestions? Thanks in advance, Oli Keller
