This looks like some problem with widgets, I'm not sure. Such errors can be 
quite frustrating, I do it like this:

- locate where the adapter is queried, this will be somewhere in the z3c.form 
package
- If not sure, use "print 'HERE I AM'" statements in the source to find out 
where the exception is raised
- When you found the code line, things hopefully resolve
- Sometimes your object/request is not marked with the requested interface, 
you can check that out with a "print 
IRequestedInterface.providedBy(myobject)" in the framework source.

I know that it is probably a bad style to temporarily modify the framework 
source but I can't think of a better solution.

Over the time you'll start to "smell" why these component lookup errors happen 
and resolve them more easily.

Maybe you did not log in into the Zope instance? You set the permissions 
to "zope.ManageContent", you could also change this to "zope.Public" and try 
it again.
