[Zope] How to obtain an instance of a subobject ?

Hi, I m totally new to Zope, and would be grateful for some answers. I have created a new product with the following structure : ProductX ZClass Y ZClass Z I have successfully added an instance of the ProductX, so I have ProductX at Tests. Now I wanted to add an object of Y in my Tests, how do I do it ? I thought that I should be able to add it by using the "add" button, but I don't see Y or Z in the list of stuff that i can add ?! I saw something in the mails about a tab for adding subobjects to the list, but i couldn't locate it. Thanks in advance for help. __________________________________________________ Do You Yahoo!?
