[Zope] problems writing unit tests

Hi there, one of the methods I call from a unittest changes a property. When called from "normal" zope it works fine. When I call the same function from a unittest it breaks saying that URL1" is not defined. Here is the code I use. The first time (no property it) works fine. The second time it breaks if self.hasProperty('poolGroup'): self.manage_changeProperties(REQUEST = {' poolGroup':= group}) else: self.manage_addProperty(id = 'poolGroup', type='string', value=group) Setting the Property like this: self.manage_changeProperties(REQUEST = None, poolGroup = group) does not generate an error, but does not change it. Any hints are greatly appreciated. Robert www.redcor.ch
