I think that Ernest has addressed this concern before. I'm fairly sure that he said something like "...you can't put the genie back in the bottle" -- meaning that once you've made one or more function calls on the RHS, they are un-retractable as would be any Java method call. Now, if all they did was change your application's state in a more or less discrete way, then you could of course pre-store that state in memory and roll it back via a custom Undo function if something goes wrong. However, if those RHS function calls that you fired off launch a rocket or something... well you get the picture. -Jason ----------------------------------------------------- Morris Technical Solutions LLC www.morristechnicalsolutions.com [EMAIL PROTECTED] phone/fax: 503.692.1088 -------------------------------------------------------------------- To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' in the BODY of a message to [EMAIL PROTECTED], NOT to the list (use your own address!)
