Re: [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

Even more disturbing, however, I frequently get the following error 
message and am not sure what it means and whether it is related to Plone 
2.0/Archetypes 1.2.5-rc2 or just Zope 2.7.

This is a clear sign of a persistency bug:

  Persistent objects must not be stored outside of their connection,
  neither in module global data structure nor as class variables.
A few days ago, I fixed two persistency bugs (one major and one minor)
in Archetypes CVS HEAD.
With these fixes, our AT based products are again refreshable (in fact,
the fix for the major bug was already sufficient for this;
occurence of the minor bug is unlikely). Let me know should you
still have problems with the fixes.
