Ooooh detach() - I like that, not used it before but it sounds perfect, thanks Martijn.
The query is part of the Jboss Rules package and while it would be nice to add a custom query to retrieve first/count results, my current job is to just replace the skin with a Wicket based web site. It's now on the list of optimisations for the next version!

Isn't it more cost efficient to apply the first/count to the query itself?
