    I am getting this null pointer when I attempt to fetched object to an object
    that was newly created.

    I get a different NullPointer if I try to set the relationship from the
    other direction.

    java.lang.NullPointerException

    Object.java:3

            at java.lang.Thread.run(Thread.java:534)

    This is the exception I am getting when I try to relation and new object to
    the fetched object. I am not sure if I am doing something wrong, but it is
    Monday so I wouldn't be surprised. This seems like it would be pretty
    common, and Ideas?
