"createInObjectManager" is uninterested in "REQUEST". It creates the new object (usually, exception when its object has a special "Destination" attribute) in the parent (aq_parent) of its object. Your "dtml-with" should place your "class1" instance correctly in the "parent position". I expect, that your "class1" does not inherit form "ObjectManager" and therefore does not have a "_setObject". In this case, "createInObjectManager" goes up another step (another "aq_parent") and reaches the folder containing the "class1" instance. It has a "_setObject", the "class2" instance is placed there, too.

Anymore info (or pointers to better docs) would be great. Thanks. You can learn about "aq_parent" in the acquisition documentation.

Search "zope.org" for it (acquisition). Dieter
