[jira] Updated: (OPENJPA-1205) Cannot retrieve
Map fields when DataCache is on
[ https://issues.apache.org/jira/browse/OPENJPA-1205?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Donald Woods updated OPENJPA-1205:
----------------------------------
Fix Version/s: 2.0.0
1.3.0
> Cannot retrieve Map<PersistenceCapable, PersistenceCapable> fields when DataCache is on
> ---------------------------------------------------------------------------------------
>
> 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
> 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.
