    Hi all, I am using OJB and I can't seem to add a record to the
    database if that object contains another object that is a) mapped in
    the mapping and b) not already in the mapping. The error I get is:

    OJB works reliably in all the other test suits:
    -- adding any object and not imposing any connections, ie, they have
    no elements that need to cascade
    -- retreiving results (either with a criteria or alll records)

    I dont know whats going on and would appreciate som ehelp - thanks in
    advance

    There was 1 error:
    1) testAddProjectWithExistingEmployer(com.joshlong.portfolio.bos.tests.PortfolioTest)com.joshlong.portfolio.PortfolioException:
    org.odmg.LockNotGrantedException: Can not lock ID:0Finished:Mon Nov 10

    Started:Mon Nov 10 04:02:34 PST 2003
    Title:Foo Bar
    Employer:
    ------------------------

      public void testAddProjectWithNewEmployer()
                throws Exception {
           // the pk for the Employer class is id and I didnt
    //set it -- I want OJB to add it as well as add the Employer
    //which also doesnt have the pk set which I presume makes it
    // add it as opposed to updating it ...

            Employer employer = new Employer();
             employer.setContactInfo("this is the contact info");
             employer.setName("le nom - " + new Date());
          employer.setDuties("a;b;c;d");

            portfolio.addEmployer(employer); // see below fo rthe code
    behind addEmployer ( Employer);

            Employer e = portfolio.getEmployerByName(name);

            Project project = new Project();
            project.setEmployer(employer);

            project.setDescription("This is a description of the
    things.");
            project.setFinished(new Date());
            project.setStarted(new Date());
            project.setName("Joshua Long");
            portfolio.addProject(project);
        }

    addEmployer is basically just a more specific method that in turn
    calls:
     void addRecord ( Object record )
          throws PortfolioException
    {
                Implementation i = OJB.getInstance();
                Database db = i.newDatabase();
                db.open("default", Database.OPEN_READ_WRITE);
                Transaction txc = i.newTransaction();
                txc.begin();
                txc.lock(record, Transaction.WRITE);
                txc.commit();
                db.close() ;
    }
