[Zope-dev] Site Error

[AP Meyer]

Maybe I just don't see it, but with the latest Archetypes from the CVS I 
  get the following error:



Site error

This site encountered an error trying to fulfill your request. The 
errors were:

Error Type
     AttributeError
Error Value
     reference_catalog
Request made at
     2004/04/06 16:23:41.266 GMT+2



What I found so far is that the reference_catalog problem only occurs in 
an instance of Project from the  ArchGenXMLComplexExample code. Maybe 
this is a known bug?

thanks
Andre
