Hibernate version:
jboss 4.0.4 ga says:
12:43:26,000 INFO [Version] Hibernate EntityManager 3.2.0.CR2
12:43:26,062 INFO [Version] Hibernate Annotations 3.2.0.CR2
12:43:26,078 INFO [Environment] Hibernate 3.2 cr4

i downloaded & install by ant the new release candidate 9 of jboss ejb3 package and there's a problem with parameter query:
i create a query:

Query queryToReturn = entityManager.createQuery(ejbQuery);

then i put the parameters... but since the upgrade i put 4 parameters in my query and it runs with 3 parameters only!!!! (and it crash because i'm expecting a single result and without a param i got 4 results)

i have a pic taken form eclipse debug: (after lunch i try to add the image) the map inside query implementations report correclty a size of 4, but there are 3 "top-level" map entry and 1 more "child" map entry inside one of the "top-level" map entry....

IMHO RC8 handles this coreclty but RC9 doesn't

P.S. rc9 installation needs a "all" jboss install configuration... next i try to do a clean installation

thanks in advice

That's it?
Give more code.

I try to explain better...
first of all i had problem with RC9 version, then i switch back and now i'm using

Implementation-Version: JBoss EJB 3.0 RC7 - FD

(taken from manifest.mf of jboss-ejb3.jar)
and i have no more this trouble.

After i create query with the previuos code i set 4 parameters to my query with:

queryToReturn.setParameter(<paramName>,<paramValue>);

then i invoke

queryToReturn.getSingleResult()

because i'm expecting a single result, but i got an Exception because i had selected 4 records... i check the database... with the 4 parameters i set i had to select only one record.... for some reason seems that 1 parameter is lost!?!?!?

With eclipse debug i see that inside query implementations the map had 3 top level parameter.entry (key,value) and inside one of these there's one more parameter.entry (key,value)

thanks to all
