Jess fires rules only while the function (run) is executing. You're actually calling (run) at the end of your script, but this call to (run) is over long before the user pushes the button -- probably before frame1 actually appears on the screen. (run) returns as soon as there are no more rules that need to be fired, and at the time you call (run) there aren't any activated rules, so the function returns immediately. You want Jess to be running after the fact is asserted. The easiest thing to do would probably be to change the (run) at the end of your script to (run-until-halt). Just make sure that's the last line of your script, because (run-until-halt) won't return until the program exits or something calls the Jess (halt) function. --------------------------------------------------------- Ernest Friedman-Hill Advanced Software Research Phone: (925) 294-2154 Sandia National Labs FAX: (925) 294-2234 PO Box 969, MS 9012 [EMAIL PROTECTED] Livermore, CA 94550 http://herzberg.ca.sandia.gov -------------------------------------------------------------------- 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!)
