Hi all,
Greetings !
On moving my plone instance from zope 2.6.1 to zope 2.7 i am getting assertionError.
The traceback details are:
Module TAL.TALInterpreter, line 189, in __call__
Module TAL.TALInterpreter, line 233, in interpret
Module TAL.TALInterpreter, line 663, in do_useMacro

Module TAL.TALInterpreter, line 554, in do_insertTranslation
Module TAL.TALInterpreter, line 751, in write
TypeError: len() of unsized object (Also, an error occurred while attempting to render the standard error message.)

Different pages are giving different TAL errors..
Why is this so, on irc i was told this is a known bug. But was unable to get any solution for the same.
How do I solve this?
Thanks & Regards,
