Re: [Zope] Error: 'in ' requires character as left operand

thanks for your response! I'm still having the problem after undoing the transaction, so I'm really confused now. worse than that, I then packed the database, so no more undos... Oops. When you pack, the previous state is safed in a file called "Data.fs.old". Thus, you may go back.

However, I expect that the new role was not your problem. I suspect a new product or a newly instantiated instance of a product to be causing the problem. Then the problem would not be in your ZODB but somewhere in the code base. Maybe, you catch the exception in "AccessControl/Role.py: 106" and print out the problem causing operands. This may give a hint where the problem lies. Dieter
