[Zope] Create or edit instance objects

[Pablo Ziliani]

Hi Tino,

so far, to edit an "iii" instance I only had to call my "MMM" method this 
way from the web:
"http://root/folder1/folder2/iii/MMM"
so method MMM used iii object values.

When the parent was a folder
"http://root/folder1/folder2/MMM"
the method itself set some defaults (even its id) to the request, so the 
instance could be created.

This worked fine placing the method in an "acquirable" folder, but as I 
said before, I´m trying "MMM" to become a class method.

The edit function worked fine by placing "MMM" in 
the "MyProduct/propertysheets/methods" folder but (of course), this way I 
couldn´t call it from a folder (to create a new instance) since it was only 
acquirable from MyProduct´s class instances.

Now, in your proposed schema, how would you call the "xxx_class_add" method 
_VIA_WEB_ for it to get "iii" instance´s values (to edit them)?

Thanks again,
Pablo.
