Martin Dirichs updated OPENJPA-1736:
------------------------------------
Attachment: OpenJPA-2.0.0_OJ1736.testcase.patch
File OpenJPA-2.0.0_OJ1736.testcase.patch contains a test case which can be
applied to the OpenJPA source and then run.
> Mappings with foreign keys as identity fields sometimes not resolved correctly
> ------------------------------------------------------------------------------

> Key: OPENJPA-1736
> URL: https://issues.apache.org/jira/browse/OPENJPA-1736
> Project: OpenJPA
> Issue Type: Bug
> Components: jdbc
> Affects Versions: 2.0.0
> Reporter: Martin Dirichs
> Attachments: OpenJPA-2.0.0_OJ1736.testcase.patch
>
>
> This is a follow-up issue of OPENJPA-1141. The solution developed for that
> issue only handled some aspects of an underlying greater problem with
> OpenJPAs mapping algorithm. This algorithm may fail under certain
> circumstances involving foreign keys used as identity fields in other
> entities. A patch with a test case illustrating this problem is attached to
> this issue. The problem can probably show up with different exceptions.
> However, the stack trace for the supplied test case is as follows:
> testEntityAsIdentityField001(org.apache.openjpa.persistence.identity.entityasidentity2.TestEntityAsIdentityFields2)
> Time elapsed: 1.656 sec <<< ERROR!
> <openjpa-2.0.0-r422266:935683M fatal user error>
> org.apache.openjpa.persistence.ArgumentException: Errors encountered while
> resolving metadata. See nested exceptions for details.
