>                 Key: OPENJPA-1205
>                 URL: https://issues.apache.org/jira/browse/OPENJPA-1205
>             Project: OpenJPA
>          Issue Type: Bug
>          Components: datacache
>    Affects Versions: 1.2.1
>            Reporter: Simon Droscher
>            Assignee: Donald Woods
>             Fix For: 1.3.0, 2.0.0
>
>         Attachments: EntityToEntityMapFix.patch

> Consider the following mapping, which uses a Map of a PC class to another PC class:
> @OneToMany(targetEntity = CatalogProductPriceImpl.class, cascade = { CascadeType.ALL
})
> @MapKey(name = "catalog")
> public Map<Catalog, CatalogPrice> getCatalogPrices() {
>   return catalogPrices;
> }
> With the DataCache on, when a product is retrieved for the first time, this map will
be correct. However, the next time it is retrieved (i.e. from the cache), what is returned
is a Map<LongId, CatalogPrice> not the expected Map<Catalog, CatalogPrice>.
> The attached patch resolves this issue.
