This is a pretty standard pattern and is called the 'sequencer pattern'. We have been implementing some of these patterns, but we don't have this one yet.

Maybe you can contribute the service (SequencerAction) back to us :). --Kurt View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128386#...
