[jira] [Commented] (OPENJPA-2325) MappedSuperClass without an @Id
causes wrong identity type for the inherited types
[ https://issues.apache.org/jira/browse/OPENJPA-2325?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13559668#comment-13559668 ]
Pinaki Poddar commented on OPENJPA-2325:
----------------------------------------
The problem surfaces when an instance of the derived class (using application identity) created via new operator is merged while an instance with the same identity value exists.

> A MappedSuperClass without a declared identity field can cause the derived classes that have decalred an @Id field to be wrongly using DATASTORE identity type because the identity type of its superclass being UNKNOWN leads the derived type to use the default identity type, which for JPA faced is set to DATASTORE.
> The suggested change modifies the logic of ClassMetaData while detecting the identity type whether it is an abstract (i.e. MappedSuperClass). Also introduced a change that distinguishes whether the identity type was ever evaluated versus whether identity type is indeterminable (i.e. UNKNOWN) which will will save few cycles for this commonly invoked operation. Previously for UNKNOWN type was indistinguishable from the case where identity type was never evaluated.
