[Zope] How to 'add' a ZClass in DTML..

For a document I can do: <dtml-call "manage_addDocument(blah, blah, blah)"> now, if I have a ZClass called STOCKProduct (meta STOCK) how can I make one in DTML? It's beyond my meagre knowledge :( Also, how to I 'initialise' properties programatically on creation of a ZClass? (ie: I want to read them in from an SQL database on creation based on the ID) I assume I put some code in STOCKClass_add, but I'll be darned if I can get anything there to work correctly :( Any help GREATLY appreciated. ------------------------------------------------------------ Stuart Woolford, stuartw@newmail.net Unix Consultant.
