    I have a nested DataContext:

    DataContext childContext = parentContext.createChildDataContext();

    I have a Master and 3 Details (1-to-many) in the parent DC (in a
    committed state), and pull the Master into the nested DC using
    localObject(). If I then do the following:

    Master childMaster = (Master)
    childContext.localObject(parentMaster.getObjectId(), null);

    Detail d = (Detail) childContext.newObject(Detail.class);
    d.setXXXXXXXX(...); // do sets
    childMaster.addToDetails(d);

    childContext.commitChangesToParent();

    childContext.deleteObject(d);
    childMaster.removeFromDetails(d);
    childContext.commitChangesToParent();

    I get an exception on the last commitChangesToParent():

    Exception in thread "main" org.apache.cayenne.CayenneRuntimeException:
    [v.3.0M1 Jul 16 2007 22:25:33] Can't build a query for temporary id:
    <ObjectId:Detail, TEMP:000004B078EB2838>

    Is this to be expected? If I change commitChangesToParent() to
    commitChanges() it works ...

    Thanks,
