CMR field "is not a cmr field". What did I do wrong?
I have this really really simple and small project with some CMR relationships, but when I try to create a simple EJB-QL query, JBoss says that my CMR field "is not a cmr field". I don't know why, I did everything my books told me. I have my code below, and this is the error it gives me:
org.jboss.deployment.DeploymentException: Error compiling EJB-QL statement 'SELECT OBJECT(osp) FROM OptimizationStaticParameter AS osp WHERE osp.optimization.name = ?1 AND osp.optimization.timestamp = ?2 AND osp.parameterName = ?3'; - nested throwable: (org.jboss.ejb.plugins.cmp.ejbql.UnknownPathException: In path field is not a cmr field: at line 2, column 71. Encountered: "optimization" after: "osp.")
The CMR relationship is a Unidirectional one-to-many relationship. OptimizationBean contains between 0 and N OptimizationStaticParameterBeans. ("An Optimization contains Static-Parameters")
Everything is REALLY simple, and it was built from the bottom up. It deploys OK if the EJB-QL queries are removed.
This seems very simple to me, and everything I have read says I am doing this right. Can someone glance and see what I did wrong? I desperately need this to continue!
Thanks to anyone!!
