---------------------------------

Greetings:

I get the exace sam error message with this hiberante query.  I should not that I am using Spring to convifgure hibernate:

return (String)sessionFactory.getCurrentSession()
        .createQuery("song.author from Song song where song.label= ? and song.artist = ? and song.title = ?")
        .setString(0,label)
        .setString(1,artist)
        .setString(2,title)
        .uniqueResult(); 

here is the trace:

java.lang.IllegalArgumentException: node to traverse cannot be null!
        at org.hibernate.hql.ast.util.NodeTraverser.traverseDepthFirst(NodeTraverser.java:31)
        at org.hibernate.hql.ast.QueryTranslatorImpl.parse(QueryTranslatorImpl.java:254)
        at org.hibernate.hql.ast.QueryTranslatorImpl.doCompile(QueryTranslatorImpl.java:157)
        at org.hibernate.hql.ast.QueryTranslatorImpl.compile(QueryTranslatorImpl.java:111)
        at org.hibernate.engine.query.HQLQueryPlan.<init>(HQLQueryPlan.java:77)
        at org.hibernate.engine.query.HQLQueryPlan.<init>(HQLQueryPlan.java:56)

        at org.hibernate.impl.AbstractSessionImpl.getHQLQueryPlan(AbstractSessionImpl.java:133)
        at org.hibernate.impl.AbstractSessionImpl.createQuery(AbstractSessionImpl.java:112)
        at org.hibernate.impl.SessionImpl.createQuery(SessionImpl.java:1623)
        ...
        at java.lang.Thread.run(Thread.java:595)

Do you know why this happens?
