session.createQuery("Select attribute from GoodsSection tgs " +
    "join gs.ascendants ags join ags.attributes attribute " +
    "where attribute.outerId = :outerId and tgs = :section ")
.setString("outerId", pOuterId)
.setEntity("section", section)
.setMaxResults(1)
.uniqueResult();

Se ve bien para mí, pero el resultado es

java.lang.IllegalStateException: No data type for node: org.hibernate.hql.ast.tree.IdentNode 
 \-[IDENT] IdentNode: 'attribute' {originalText=attribute}

    at org.hibernate.hql.ast.tree.SelectClause.initializeExplicitSelectClause(SelectClause.java:145)

    at org.hibernate.hql.antlr.HqlSqlBaseWalker.statement(HqlSqlBaseWalker.java:229)

¿Por qué? Qué tiene de malo?
