> Project: OpenJPA

> Reporter: David Minor
> Attachments: openjpa_superclass_join.patch,

>
> When the DataCacheStoreManager loads an object whose (table join strategy)
> superclass contains an eager to-many field, and this is the only field
> selected in the superclass, and when one or more fields are selected in the
> subclass, openjpa fails to create a join between the subclass and superclass.
