Subject [jira] Updated: (OPENJPA-527) Merge of new one-to-many list only persists last element.
Date Thu, 28 Feb 2008 18:11:51 GMT


Gil Markham updated OPENJPA-527:

    Attachment: mergetest.tgz

This tgz file contains a standalone maven project that illustrates the problem.  You should
be able to simply run 'mvn test' to run the failing junit test case against an embedded hsql
database.  SQL logging is turned on in the persistence.xml to show that only one INSERT is
run against table 'B' even though three objects should be persisted.

> If a transient new object is merged containing a one-to-many (with elementjoincolumn)
list of transient new objects the last object in the list is the only object persisted.  This
functionality has changed since 1.0.1 as the same code worked properly with that version.
> Calling persist using an equivalent object works properly but this should work in both
> I'll attach a tgz of a maven project that illustrates the problem.  The project uses
hsqldb internally and should run stand alone without anything but maven and java installed.
