[Zope3-Users] formlib problem

Hi Jim, 
 the Items object is my object, linked to my items, table which implements the IItems interface I use for my form:
 
 from neteven.interfaces.items import IItems
 from zope.formlib import form    
 
 class ItemsForm(form.EditForm):
     form_fields = form.Fields(IItems)
     form_fields = form_fields.omit('dateLastUpdate')
 
 Items is defined this way:
 
 from zope.interface import implements
 from sqlobject import *
 from sqlos import SQLOS
 from neteven.interfaces.items import IItems
 
 class Items(SQLOS):
     implements(IItems)
     
     class sqlmeta:
         table = 'items'
 ....
 
  When I add this zcml declaration :
 <browser:page
       for=".interfaces.items.IItems"
       name="edit.html"
       class=".forms.items.ItemsForm"
       menu="zmi_views"
       title="Edit a Item"
       permission="zope.ManageContent"
       />
 everything works fine from the ZMI (I created simple containers to test that).
 
 My JSON server side code is:
 
 def getItemEdit(self, itemId):
         item = Items.get(itemId) #a sqlos function to get an Item instance from the table given its Id
         return ItemsForm(item, self.request)()
 
The fact is I don't use any page template right now ( though I might do this later to have a nice GUI).
 
 Thanks,
 
 Stéphane

Maybe these questions will help.

What is an Items object? 
Why are you calling a page template that needs title_or_name with an 
Items object as the context?
