Hey all,

I'm getting the following error:

Code:
java.lang.IllegalStateException: No data type for node: org.hibernate.hql.ast.tree.AggregateNode
\-[AGGREGATE] AggregateNode: 'max'
    \-[IDENT] IdentNode: 'id'

   at org.hibernate.hql.ast.tree.SelectClause.initializeExplicitSelectClause(SelectClause.java:167)
   at org.hibernate.hql.ast.HqlSqlWalker.useSelectClause(HqlSqlWalker.java:831)

   at org.hibernate.impl.AbstractSessionImpl.createQuery(AbstractSessionImpl.java:135)
   at org.hibernate.impl.SessionImpl.createQuery(SessionImpl.java:1651)


This is a product of the query I'm making into my PostgreSQL database:
Code:
FROM table WHERE value = (SELECT max(value) FROM table WHERE id = 'myID')


There are multiple entries associated with an id each with their own value. This query should return the entire row that has the max value.

The query is executed with this code:
Code:
FooBar myFooBar = (FooBar) session.createQuery(queryAbove).uniqueResult();


Any help is appreciated.

Thanks,
glittle
