[Zope-dev] Using PropertySheets

Hi everbody, I've played a bit with the PropertySheets interface and I wanted to create two Stylesheets. Everything works fine, but ... * I don't get the management tabs in the propertysheet/manage method. Perhaps a permission problem? * I can't pass a default value to a tokens property. How to? * I can't pass a default value to a boolean property. How to? Could someone please give me some example code or hints? Thanks in advance Eric
