[jira] Created: (OPENJPA-207) failure when composite ID w/ another
composite ID as a field
failure when composite ID w/ another composite ID as a field
-------------------------------------------------------------
Key: OPENJPA-207
URL: https://issues.apache.org/jira/browse/OPENJPA-207
Project: OpenJPA
Issue Type: Bug
Affects Versions: 0.9.6
Environment: derby
jdk 1.5.0_07
Reporter: Jeffrey Blatttman
Priority: Minor
Attachments: book.zip
see attached test case: entities Library, Book, and Page. there is a one-many bidirectional relationship between Library and Book, and Book and Page. a Library's ID is simply it's name. a Book's ID is it's name, plus it's owning library's ID. A Page's ID is it's number, plus it's owning Book's ID.
this arrangement results in composite IDs for Book and Page. and moreover, Page's composite ID, PageId, contains a page number field plus a BookId. however, this arrangement results in an exception at runtime w/ the included test case ...
...
Caused by: java.lang.ClassCastException: org.apache.openjpa.util.ObjectId
at com.mycompany.book.Page.pcCopyKeyFieldsToObjectId(Page.java)
at org.apache.openjpa.util.ApplicationIds.create(ApplicationIds.java:383)
at org.apache.openjpa.kernel.BrokerImpl.persist(BrokerImpl.java:2349)
note that if i remove the bookId field from PageId, the test case succeeds.
also note that this problem is also observed against a trunk field from march 3 (0.9.7 snapshot).
