hi there

I keep running into problems with my Address Book example. This one should be simple but I can't find the problem. I may have spent too much time looking at it. I get this error after I add an "entry" and then try to edit it:

No data seems to get saved in the street field when I use the addform either.

I'll put the code I'm working with at the bottom.

I have been trying to get a good understanding of ObjectWidget and have been have a really hard time. I got most of the code layout for this from here: http://www.mail-archive.com/zope3-users@zope.org/ msg00917.html

I'm using Zope 3.2.1

It seems like since it's a security problem I should be able to fix it by changing something in configuration.zcml but I just can not see anything I'm missing. Any help would be appreciated.

thanks.
