We were using the same queries in CR1, but with GA we get errors. Error messages like | 2007-05-14 16:34:25,285 ERROR [org.hibernate.impl.SessionFactoryImpl] Error in named query: Weight.BlockedWeights | org.hibernate.QueryException: illegal attempt to dereference collection [dmweightbe0_.UNID_UOID.statusCause] with element property reference [reference] [SELECT o FROM org.ictrace.server.pm.DMWeightBean o WHERE ( o.weightTime >= :weightTime ) AND ( o.declaration.species = :species ) AND ( o.statusCause.reference = :reference ) ] | The UNID_UOID referenced is the primary key for the table. Is there a way to revert to the old behaviour? Thanks for the help, Joachim View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4045545#...
