> OpenJPA cannot do a SELECT with parameterized JPQL queries and EmbeddedId.
> E. g., following configuration doesn't work:
> There a two entities: EntA and EntB. Both have a composite primary key (EntAPK and EntBPK) that is used as an embedded id. I want to execute following query:
> SELECT a FROM EntA a WHERE a.entB=:entB
> Needlays to say, the parameter is an object of the entity EntB.
> While executing the getResultList method I get following exception:
> Caused by: java.lang.ClassCastException: com.example.EntBPK cannot be cast to [Ljava.lang.Object;
