Hi,

  I just read this thread. Wich seems really interesting.  Is there an
example on how to use Async Notifies?  I look at it a couple of months
ago and found it not sufficient for my needs.  I need to implement a
notification mechanism to clear data from caches in my application on
data update.

Is this change allow me to do that .. ?  That will be so nice :-)

If yes it's that possible to get a small example on how to use it.

Thanks!
/David
