Hello,

I'm new to the list, so please forgive me if I miss some common netiquette that is expected on this list.

I'd like to try to create a patch to solve 869, as well as support querying of collections of composite types.

First, are there any guidelines of what I should and shouldn't do? I'd love to clean up the implementation of CriteriaQueryTranslator while I'm working in there, but if that would disqualify my patch, then of course I should avoid that ;-)

Second, I'm having a little trouble finding the metadata I need to implement CriteriaQueryTranslator.getColumns() and CriteriaQueryTranslator.getType() for composite collections. By that point, I have access to: CollectionPersister, propertyName, and sqlAlias. CollectionPersister.getElementType() returns a CompositType that appears to be empty.

Thanks,

Daniel.
