Hi, We have build a sort of cmf with a lot of Zclasses. For over a year this worked without any problems (Zope 2.5.0). The properties of these classes are manipulated from our own user interface/cmf with python scripts with statements like this: context.propertysheets.properties.manage_changeProperties(xxxxx=xxxx) Now we have to implement a project where we have to use exuserfolder. Now things are going wrong. We get the following (see below, also when the user has the manager role) error when we edit the properties with our own interface. However in the manageinterface of Zope we can change the properties with authentication from exuserfolder. The weird thing is that with the standard user folder it works fine from within our applications. Any thoughts?
