    yes, we have auto-increment on that table. how do i invalidate the caches? i know there is a invalidateObjects method, but is this the way to do it?

    You know, sometimes simple and fast is a good way to do things. Do
    you have an auto-increment PK in that table? Would be helpful. As for
    Cayenne, can you can flush (invalidate) any active DataContexts (at
    least the objects for that table) when the load occurs?

    /dev/mrg
