Hi Mark,
I guess that the buildUrl function in ditto class should unset the start param in querystring.
For instance if you are page 3 of your ditto listing and click a tagLink the &start will be part of the url.
So if you don’t have enough docs with this tag, ditto will return no documents found.
As the &start is passed to buildurl as a param when creating the pagination I think we can unset it as id and q.
:-)
Fixed in latest SVN. Thanks for the find.
