Hello I have another problem with Zope1_11_0pr1: I have done the zclass like the CD exemple, just it's called 'Shipment' and has a lot of properties in a sheet called Shipment_Info. My problem is that only the superuser (or a user with manage role) can modify the properties of the newly created class instance. My 'addForm' method call a 'Create' method like: Creating request...<br> <!--#with "Shipment(REQUEST['id'],REQUEST)"--> Filling values...<br> <!--#call "REQUEST.set('Status','New')"--> <!--#call Update--> <!--#/with--> Done... The 'Update' method is a class method like: <!--#call "propertysheets.Shipment_Info.manage_changeProperties({ 'Status' : REQUEST['Status'], })"--> My AccessControl python files are now up to date and handle nicely the added user-folders. I have try adding all the possible permissions to the zclass, I all the time end up with the login+password prompt windows.If I cancel it, Zope says:'You are not authorized to access manage_changeProperties.' The security settings for the properties-sheets is set to allow 'Anonymous' and my user Role ('Test'). My zclass methos 'Update' security has the 'Manage properties' permission mapped to 'Manage properties', the same for 'Access contents information','view','View management screens'. My zclass has all the permission on for anonymous and the 'test' user. I have also try to add local roles to my test user: no luck, also adding manage role. Another remark: the instances are created with default permission : just the 'Acquire permission settings?' is checked. If I un-check them and check all the permissions for anonymous or my user, still only the superuser can change the properties. So: am I the only one with this problem? Has someone a solution? NB: also has someone solved the request timeout with IE?? I have also the 'to many open file problem', the python process get one more open file at every site access, until the OS limit: 256 in my case (linus 5.1) Thanks for any help. Gilles
