I did but had an exception with it. I had to modify the sources of
hibernate and recompile it to make it work with mdarad.
The problem was located in the source code of the class
org.hibernate.mapping.Collection in the method getComparator(). The
highlighted portion of the following code was comparator!=null
and prevented from returning a valid comparator.
public Comparator getComparator() {
if(comparator==null &&
comparatorClassName!=null) {
try {
setComparator( (Comparator) ReflectHelper.classForName(
comparatorClassName ).newInstance() );
}
catch (Exception e) {
throw new MappingException( "Could not instantiate
comparator class: "
+ comparatorClassName + " for collection " +
getRole() );
}
}
return comparator;
}
If you have any questions, contact me.

I've seen a few threads of hibernate on this and some seem to suggest
to move to hibernate 3.1 (that is still in release candidate 2).
Phil I think you tried to merge to hibernate 3 no? Any problems?

I just found a bug that I hadn't seen before and want to know if you
guys have noticed it.
In any application started with StartTemplate.zuml (so with the default
Logins) I get the following error when trying to add a LoginRole to a
newly created LoginGroup:
