[hibernate-dev] HHH 869 (Collections of value type in the Criteria API).

[Daniel Pitts]

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.
