I had a closer look at it.
The problem exists with Gadfly as well. It only occourse when
you use a database connection and test it with some test SQL.
This is a limitation in Connection.py .
If you use ZSQLmethods, you will not have this problem.

Reason: ZSQLmethods carry their SQL template as a property.
A simple connection does not, since it has no permanent
property for the (temporary) SQL string. The alternative would
be to pass the SQL string as a parameter to the "next 50" link.
This isn't very nice since this is a GET request, which is limited
in size. But for not too large test SQL input, it will work.

Here the patch:

Edit the file "Connection.py"  (dir D:\Zope\lib\python\Shared\DC\ZRDB)

Locate line 189 ff in manage_test:

        if REQUEST is None:
            return result       #return unadulterated result objects

Add the following code snippet:

        #CT: passign the query parameter to the "next 50 results" link
        import urllib        
        REQUEST.environ["QUERY_STRING"] = "query=" + urllib.quote(query)


That's all, folks. The query will now be rendered as part of the
URL, and it works.
