 Post subject: coalesce w/ subquery problem

Hibernate version: RC8 with PostgreSQL 8.1.4

I cannot use coalesce with a subquery. If I remove coalesce and then add it manually to the generated sql the raw sql executes as expected and the coalesce works fine when there is no subquery.

Code:
select reclassify as reclassify,
         coalesce((select sum(c.numPieces)
                        from Coupling c
                        where c.state.parentState.id=reclassify.id ),0) as numCompleted,
coalesce(reclassify.id,0)                               
from Reclassify reclassify


I get the following error when the hql query is parsed. I would greatly appreciate any comment, workaround, or solution.

Code:
java.lang.IllegalStateException: No data type for node: org.hibernate.hql.ast.tree.MethodNode
+-[METHOD_CALL] MethodNode: '('
|  +-[METHOD_NAME] IdentNode: 'coalesce' {originalText=coalesce}

Wrapping the coalesces as follows worked coalesce(sum(c.numPieces),0)

Code:
select reclassify as reclassify,
(select coalesce(sum(c.numPieces),0) from Coupling c where c.state.parentState.id=reclassify.id ) as numCompleted,
coalesce(reclassify.id,0)                               
from Reclassify reclassify
