    Thanks for helping me out with this.

    I have one comment (for the log, perhaps others want to try that as well).

    > // be shared by multiple DataContexts.

    There is no setChannel method on the DataChannel Interface. I guess this
    is a typo and should read like this?:

    DataChannelCallbackInterceptor postInterceptor = new
    DataChannelCallbackInterceptor();

    Most of the callbacks are working now. But I can't seem to get the
    prePersist method work as expected? PrePersist is never called, although I
    registered all the possible events. Do you have an idea?

    Thanks again,
    Adrian
