Hi,

I've started seeing errors like this:

------ 2001-02-27T11:18:34 ERROR(200) ZODB Couldn't load state for

Traceback (innermost last): File E:\Zope\23C76D~1.1B1\lib\python\ZODB\Connection.py, line 477, in setstate

AttributeError: 'None' object has no attribute 'load'

...popping up from time to time. I think they're coming from a product we've written, but beyond that I have no idea what's going on. How would I begin to dig? Is there any way I can find out the id of the object that OID corresponds to?

cheers,

Chris

I hazard a guess that you're changing a mutable attribute of a persistent object, without doing a _p_changed=1 on your persistent object. -- Steve Alexander Software Engineer Cat-Box limited
