[Zope] Adding a document using a form

[Mats Myrberg]

Hi,

I am a complete Zope newbie so have some patience with me.  Mike suggested a
way to Lalo to move the code that creates the DTML Document into a DTML
Method.  I tried this method but I get the below error and stack trace.  It
seems that the call to self._setObject is failing.  What is self in this
case?  BTW the add form is living in a folder called Products in the root
folder.  My code for the DTML Method is:

<dtml-call "Products.manage_addProduct['OFSP'].addDTMLDocument(id, title)">

It does not seem to matter whether I prepend the Products object on the call
string or not.

Hopefully I will be able to contribute to the list as I come up to speed.
