Subject [jira] Commented: (OPENJPA-967) JPA2 Query support for selction of KEY, VALUE, ENTRY of a Map value
Date Sat, 04 Apr 2009 01:36:12 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-967?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12695660#action_12695660
] 

Catalina Wei commented on OPENJPA-967:
--------------------------------------

The initial implementation for embeddable Map Key materialized the embeddable's owning entity,
which from query result standpoint, is undesirable side effect.
The revision r761851 has reworked on the support for embeddable Map Key.
It is no longer materializing the owner entity of embeddable Map Keys.

However, more rework is needed to move function performed in PCPath.selectEmbededMapKey()
and loadEmbeddedMapKey() methods to relation's MapTableField strategies.
