[Zope] Create or edit instance objects

[Tino Wildenhain]

Hi Pablo,

sorry, I misread you originally post.
I see the solution in using not the same but a similar
method to create and to manage.
Just put the MMM method either in the root folder or
even better subclass Folder and put this method in it.
This simply should get all parameters and call manage_addProduct
with the class you want.

The other method, also called MMM in the zclass you added can
edit on the current object.

Would this solve your problem?

Regards
Tino
