Oops. Sorry. I was thinking that products were considered zope-dev. I
switched my subscription to zope.

Ok. An example problem I have is that my zope addon will manage tasks in a
schedule. There would be a Task object and each time the user wants to add a
new task, a new Task object needs to be created in the ZODB.

I like to have a seperate object that is not persistent that acts as a
client interface (client programs can make XML-RPC calls to it). So the
client program would make an RPC call such as createTask() and the client
interface object would then do the work of creating a new persistent Task
object in the ZODB. The client interface object is published via XML-RPC,
but the Task objects are not (they are implementation, not interface).

So I guess the following code would do that in the createTask() method...

afolder = myobject.restrictedTraverse('/path/to/folder/that/contains/Task/objects')
manage_addMyThing(afolder,'new_id',...any other needed parameters...)

Is this a sane design in Zope or am I thinking in J2EE?

Yes, yes, and quite a few.
