    Hallo!

    My first question: How can I get the next autogenerated ID for a special
    table from cayenne? Because I want that even unregistered objects can
    have an ID.
    DbAdapter.getPkGenerator().generatePkForDbEntity() is only good for
    registered objects.
    And I don't understand what DbAdapter.getPkGenerator().reset() will do.

    The second question: How can I use unregistered objects?
    I mean I can't do sth. like this:
    TimeInterval ti = new TimeInterval();
    ti.setRoom(new Room());

    The Stacktrace:
    java.lang.NullPointerException
    at org.apache.cayenne.CayenneDataObject.setToOneTarget("room",room,true)
    at caybug.TimeInterval.setRoom(TimeInterval.java:10)

    Thank you,
    Peter Karich.
