After the object is fully created and has received its portal_type, the
TypesTool calls ob.notifyWorkflowCreated() which calls
portal_workflow.notifyCreate(ob) which inserts the object into its
relevant workflow.

Well it works but is a bit of a hack.

The fundamental problem you have is that you'd like a hook to be called
just after full CMF object creation. There should be one, and I'll add
one to CVS when I have the time (it's easy, in _finishConstruction).

But in the meanwhile it's probably simpler to overload
notifyWorkflowCreated in your product:

    def notifyWorkflowCreated(self):
        MyProduct.inheritedAttribute('notifyWorkflowCreated')(self)
        # now do post-creation stuff
        # ...


HTH,

Florent
