Peer to peer method calls are often problematic - if you break an app down into all of its levels of abstraction, nearly all calls should be 'down' (toward lower-level code). Any 'up' calls should be viewed with suspicion. Calls along the same level also need to be looked at closely to ensure that the level is coherent and implements a consistent set of responsibilities. It's interesting to see that this fairly innocent topic - transactions - opens up such a complex can of worms in terms of layered design! :) -- Sean A Corfield -- http://www.corfield.org/blog/ "If you're not annoying somebody, you're not really alive." -- Margaret Atwood ---------------------------------------------------------- You are subscribed to cfcdev.
