[Zope3-Users] Error when calling addform

Hi Florian

> Subject: [Zope3-Users] Error when calling addform

> Hello,
> I have an addform registered:

>     <addform
>         label="Add Blog Comment"
>         name="AddBlogComment.html"
>         schema="..interfaces.IBlogComment"
>         content_factory="..blog.BlogComment"
>         permission="Blog.AddComment"
>     />

The add form renders the __parent__ field
which you can avoid by defining the fields=""
in the add form directive.
