[Erp5-dev] odd problem with portal in portal_types actions

[Lukasz Nowak]

Hello,

Situation: ERP5 running fine. Accessing object type Person with condition in 
actions like that:

python:portal.restrictedTraverse('accounting_module', None) is not None

Runs fine. But while accessing Organisation (while using erp5_accounting) 
gives me traceback (attached). I do not know even how to hunt that problem.

Bye,
Luke
