It seems to me that what you are really doing is customizing the 
search skin that is linked to by the worklist links so that it reports
information specific to the content you are listing - which is a
particular ZClass in this instance.

What you ought to do is create a separate workflow for this content
type, and have it's worklist entries link to a customized search skin.

The problem with doing this is that this search skin is used by
the site's generic search functions.

TALES usually produces arcane error messages, but I expect the problem is 
likely to be that your customized search skin is being called with just the 
state you're interested in, and is fetching any content with that state set 
in whatever state variable your workflow is using. The moment it comes to
render a content object without the properties you want, it spits the dummy.

Try setting the worklist URL to something like:

%(portal_url)s/search?review_state=pending&Type=MyZclass

or use meta_type=MyZClass, if that doesn't work. If that works out, go about 
customizing a worklfow that uses worklists that call your customized search 
page.
