[Zope] Properties in ZClasses???

I tried the example from Amos to generate a zclass and instances from it. I can generate the instance, but in can't get a handle to the properties. There is no Properties tab in the manage_workspace screen. I have seen the comment in the automatically generated CDClass_add DTML method. There is something like <!--#call "propertysheets.Basic.manage_editProperties( REQUEST)"--> Is Basic the same as cd_info? Where is the 'common' link? Surprisingly it functions for all other people on the list. Where should I look for errors? Thanks in advance __Janko
