Ah... I was thinking that part was some sort of generic example.
Alright, I added that code and now my component
"ComponentLookupError" cleared up. However I'm now having another
problem. When I add a new
I am getting a "ForbiddenAttribute" error. I can run the addform
with out any errors but if I editform the "street" field is blank
(even though I added some text to it when I added it). Then if I
makes some changes to the fields and try to save my changes I get one
of these:
ForbiddenAttribute: ('street', at 0x405d3b0>)
Anytime I've seen this in the past it means there's a permission
problem. So I played with the security setting in configure.zcml
some but I could not find anything that helped.
Judging from the error message it looks like it's trying to look up
the security settings for "street" in entry.ABookEntry. Which would
kinda makes sense, and then it should be looking instead in
entry.StreetAddress, but I don't know how to make it do that. I'll
include my code again too.

[Zope3-Users] zope.schema.Object and custom widgets in formlib
hi there I am having trouble getting form's generated for zope.schema.Object. After doing some more reading it looks like I should be using formlib instead of zope.app.form.browser.add.AddView and zope.app.form.browser.editview.EditView (my new code will be at the bottom) Which is fine because I was really having trouble getting zope.schema.Object to work properly. Of course, now I am running into the same basic problem with formlib. It looks like I need to specify some sort of custom widget for my zope.schema.Object. If I don't I get the same ComponentLookupError I was getting with the old system. I tried the zope.app.form.CustomWidgetFactory, and that actually got that part of the form to show up but it didn't work right. If someone could tell me what I should be doing that would be great. Also one other kinda bizarre thing, in my formlib form all the button text and messages where in German (I think, my German is a little rusty). An aside... I have been really surprised by the lack of other people having the same problems or working examples else where. I think I'm trying to do something very basic that would come up in lots of applications. This makes me think that I'm going about this the wrong way, or the solution is very simple and I'm just being too dense to get it. So basically, if anyone out there has some commentary on my approach to this problem I would really appreciate it. thanks. -jachin # -=interfaces.py=- from zope.interface import Interface from zope.schema import TextLine, Int, Object class IStreetAddress(Interface): """A street address""" street = TextLine( title=u"street", description=u"", required=False) class IABookEntry(Interface): """An address book entry""" streetAddress = Object( schema=IStreetAddress, title=u"Street Address", description=u"", required=False) firstName = TextLine( title=u"First Name", description=u"", required=False) # -=entry.py=- from zope.interface import implements from zope.formlib import form from zope.schema.fieldproperty import FieldProperty from zope.app.form import CustomWidgetFactory from zope.app.form.browser import ObjectWidget from persistent import Persistent from interfaces import IStreetAddress from interfaces import IABookEntry class StreetAddress(Persistent): """The Street Address object.""" implements(IStreetAddress) class ABookEntry(Persistent): """The Address Book Entry object.""" implements(IABookEntry) streetAddress = StreetAddress firstName = u"" class ABookEntryEditView(form.EditForm): form_fields = form.Fields(IABookEntry) form_fields["streetAddress"].custom_widget = what should go here? http://namespaces.zope.org/zope"; xmlns:browser="http://namespaces.zope.org/browser";> ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
