[Zope-dev] problem adding ZClass instances via DTML

[Gilles Lenfant]

Mark,

It seems you forget the id of your new object !!
I use do do it in Python script (easier for testing initial data from =
request). But you can translate in DTML if you prefer...
# Test initial data from REQUEST and redirect somewhere if required
...
# Create the new ZClass based object
newobject =3D =
somefolderishobject.manage_addProduct['MyProduct'].MyZClass.createInObjec=
tManager(newId, context.REQUEST)
# May add computed values to properties
props =3D {}
props['created'] =3D DateTime()
props['creator'] =3D context.REQUEST.AUTHENTICATED_USER.getUserName()
...
newobject.propertysheets.mypropertysheet.manage_changeProperties(props)
# Redirect somewhere or return the object or whatever

HTH
