Well, I am sorry to send three messages a day, but I am really desappointed... I use the following code: <dtml-with "manage_clone(livre1,Key,REQUEST)"> <dtml-call "manage_changeProperties( EntryType=REQUEST['Type'], author=Author, title=Title, year=Year, publisher=Publisher, volume=Volume, adress=Adress, edition=Edition, month=Month, note=Note )"> </dtml-with> (Author, Title..... are knowed because in a dtml-let flag....) Well, livre1 is a object created by a SFactory (a product contening a ZClass with a propertysheet) Zope do not give me any error, instantiate the new object, but does not change the properties of the new object..... :^( does anybody can tell me why????? I have seen a function "manage_afterClone" in the ZQR... do u know what is it? Thanks... and sorry for all my emails...
