> Say you have an EntityA which is annotated as @Embeddable and an EntityB which contains a mapping like
> @PersistentCollection(elementEmbedded = true, elementType = EntityA.class, fetch = FetchType.LAZY)
> private List<EntityA> list;
> Now if you remove an entry from the list of a persistent EntityB and commit the transaction it leads to the following exception:
> Caused by: <openjpa-1.1.0-runknown fatal user error> org.apache.openjpa.persistence.ArgumentException: Could not locate metadata for the class using oid "org.apache.openjpa.datacache.DataCachePCDataImpl@8c248cb" of type "class org.apache.openjpa.datacache.DataCachePCDataImpl".

>         for (Iterator itr = data.iterator(); itr.hasNext();)
>              ret.add(toEmbeddedField(sm, vmd, itr.next(), fetch, context));
> // no break
> should probably be:
> case JavaTypes.PC:
>     if (vmd.isEmbedded()) {
>          for (Iterator itr = data.iterator(); itr.hasNext();)
>               ret.add(toEmbeddedField(sm, vmd, itr.next(), fetch, context));
>          return ret;
>     }
> // no break
> At least it worked for me this way.
