Subject ArgumentException: Failed to execute query
Date Fri, 11 Feb 2011 07:09:10 GMT
Hi all, I have relatively complex entities (compound ids and id classes) but
a really simple query:

select o from ObjectItemAssociationStatus o  where o.ix = ?1 AND o.rptd.id =
?2

Nevertheless I get the following exception (I can post the entities if it
helps...)

org.apache.openjpa.persistence.ArgumentException: Failed to execute query
"select o from ObjectItemAssociationStatus o  where o.ix = ?1 AND
o.rptd.id= ?2". Check the query syntax for correctness. See nested
exception for
details.
