Subject [jira] Created: (JDO-426) NullCollectionsAndIsEmpty does not unset mapped side of relation

NullCollectionsAndIsEmpty does not unset mapped side of relation
----------------------------------------------------------------

                 Key: JDO-426
                 URL: http://issues.apache.org/jira/browse/JDO-426
             Project: JDO
          Issue Type: Bug
          Components: tck20
    Affects Versions: JDO 2 final
            Reporter: Abe White


org.apache.jdo.tck.query.jdoql.NullCollectionsAndIsEmpty uses its localSetUp() method to null
the projects of an Employee.  However, the Employee.projects field uses mapped-by in its mapping,
and per section 15.3 of the JDO 2 spec, that means changes to it aren't reflected in the datastore.
 To fix, add the following lines after retrieving "emp1" but before nulling its projects in
localSetUp():

        for (Iterator itr = emp1.getProjects().iterator(); itr.hasNext();)
            ((Project) itr.next()).removeMember(emp1);
