SELECT r FROM com.company.Toplevel AS r WHERE r.toplevel=? AND rec.productDetail.attributes[?]=? 

Also my recent post: http://forum.hibernate.org/viewtopic.php?t=966374&start=0&postdays=0&postorder=asc&highlight=

This testcase has been tested with 3.1.3 and 3.2.0-ga.


2nd problem:

There is also another situation in the testcase which I found through serendipity which causes a NPE inside hibernate because I misspelled "r" as "rec".  Check out the commented out section and swap over the createQuery() lines to demonstrate that NPE.
