[Zope-dev] Auto Generated Add Forms

[Rowan Woodhouse]

Hi,

I'm trying to use auto-generated add forms in Zope 2.10-6 (Ubuntu) with 
Five but I'm having some trouble getting them to work. I've added the 
section below to my configure.zcml:

<snip configure.zcml>

   <browser:addform
       schema=".democontent.IDemoContent"
       content_factory=".democontent.DemoContent"
       name="addDemoContent.html"
       label="Add Demo View"
       permission="zope2.ViewManagementScreens"
       />

</snip>

But when I try to open the page I get the following error:

2009-01-22T02:01:12 ERROR Zope.SiteErrorLog

I've Googled about for an answer but the only reference I can find is this:

http://mail.zope.org/pipermail/zope/2007-November/172544.html

which didn't have a reply (not one that I could find anyway)

Does anyone have any ideas about what I am doing wrong, or how else I 
can get auto-generated add forms working for a Five product?

Thanks,
Rowan
