RE: [Zope] Problem migrating from 2.6.3 to 2.7

13 Feb 2004

      ...
Hello,
I've just switched to 2.7 from 2.6.3 and everything seems to work well
except for one rather bizarre event:
I have a specific content type that can't be viewed, accessed or otherwise
used/viewed in any way without sending Zope into an infinite loop!
Here's the error I get:
Zope Error
Zope has encountered an error while publishing this resource.
Error Type: RuntimeError
Error Value: maximum recursion depth exceeded
---------------------------------------------------------------------------
Thanks for the tip, but I doubt that's it ... I simply can't access the
object it seems, not even in the ZMI, where I have no special management
templates defined (I like to always use the CMF skins).  Also, when I have a
template somewhere that has something like
"here/badobjectinquestion/absolute_url" I also run into this error.

The problem look sppretty "fundamental" to the way ZPublisher works in
relation to this content type.

I'll try to hunt further today ...

Thanks again!

J.F.

I had a similar problem tough I do not recall if it was caused ba a 
switch to 2.7
It was caused by a page template in which I had a test for the existence 
of  something (I do not recall the exact circumspects)
It was something like:
tal:define xx  here/myobject
tal:condition=" xx "
this I had to change to
tal:condition="python: if xx == None"

This is a CMF Content Type of the simplest kind really ... But this looks
like it's not a CMF specific problem.
I've attached the full definition for the content type below my signature
in
case it helps ...
Anybody know what could be causing this ???
Thanks,
