I am starting to use ZClasses for the first time and I have noticed some funny behaviour with the tabs. I am finding that they are not all always visible in the management screens. I have subclassed a container object, and separately a DTML Document. In both cases, if I create a property sheet and add it to the views, then go to the management area and create an instance of these objects, I loose some of the other tabs when I click on the property sheet that I created. On the DTML Document it is the Edit tab that vanishes, in the Folderish object it is the contents tab that disappears. Is this expected behaviour or have I done something wrong?
