Subject [jira] Updated: (OPENJPA-1884) CacheStoreMode.REFRESH is not recognized for entity manager refresh operation
Date Sat, 04 Dec 2010 06:46:10 GMT

     [ https://issues.apache.org/jira/browse/OPENJPA-1884?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jeremy Bauer updated OPENJPA-1884:
----------------------------------

    Attachment: OPENJPA-1884.patch

Attaching fix and updated test code.  In addition to handling updates, this fix also purges
entries from the L2 when the property javax.persistence.cache.storeMode is set to CacheStoreMode.REFRESH
and the refresh operation determines the entity no longer exists in the underlying datastore/database.

> Specifying the "javax.persistence.cache.storeMode" property with value CacheStoreMode.REFRESH
does not refresh the contents of the L2 cache when used with the em.refresh(entity, props)
operation.
> OPENJPA-1578 corrected this a similar issue for the em.find() operation, but not em.refresh().
 A simple port of the changes from 1578 (which simply configure the store mode in the fetch
plan) to the refresh operation did not correct the problem.  It appears that more work needs
to be done in the underlying refresh logic to produce a cache refresh.
