am getting in a pickle with a parent-child relationship and CMR. JBoss 3.2.5 is not
wanting to deploy - claiming a CMR field error. Should I be using a finder here? Not
sure. Please forgive newbie question...
22:51:48,467 ERROR [EntityContainer] Starting failed
jboss.j2ee:jndiName=ejb/pixStore/Tag,service=EJB
org.jboss.deployment.DeploymentException: Error compiling EJB-QL statement 'SELECT
OBJECT(p) FROM Tag p WHERE p.Parent.id = ?1'; - nested throwable:
(org.jboss.ejb.plugins.cmp.ejbql.UnknownPathException: Unknown cmr field in path: at
line 1, column 43. Encountered: "Parent" after: "p.")
TIA, Mark.
