If both rules are in the same agenda group you can use lock-on-active instead of no-loop:

It is so because that's what you're telling the system to do. :) The no-loop modifier only prevents a rule's conditions from infinitely re-evaluating the tuples modified by it's own action, not the actions of other rules.  So when rule "Area_EstimatedRval_test_10-01-09_12-31-14" modifies a Para_2483 it will be reconsidered by the conditions in "Area_EstimatesRval4_10-01-09_12-31-14".  The only way to prevent "Area_EstimatesRval4_10-01-09_12-31-14" from firing again is to craft it's conditions such that they're no longer true. (maybe "fid2329 != eid2143" since that contradicts what "Area_EstimatedRval_test_10-01-09_12-31-14" does, but I don't know if that makes sense for your rules.) --- On Wed, 5/12/10, Puneet duggal <duggalpunit@gmail.com> wrote: From: Puneet duggal <duggalpunit@gmail.com> Subject: [rules-users] Problem in update() method To: "Rules Users List" <rules-users@lists.jboss.org> Date: Wednesday, May 12, 2010, 10:54 PM   hi frnds i am having problem  with update() method when i call update method  from first rule it calls  second rule and goes in infinite loop calling the second method rule again and again why is it so ?? rule "Area_EstimatesRval4_10-01-09_12-31-14" date-effective "01-Oct-2009" date-expires "31-Dec-2014"  salience 5  no-loop true   when  objectP2483 : Para_2483( (fid2329>=0);    then  objectP2483.setFid2339(objectP2483.getFid2338() *3.1);update(objectP2483);   rule "Area_EstimatedRval_test_10-01-09_12-31-14" date-effective "01-Oct-2009" date-expires "31-Dec-2014"  salience 5  no-loop true   when  objectP2483 : Para_2483( fid2339>0);   then  System.out.println("Area_EstimatedRval_test_10-01-09_12-31-14");  objectP2483.setFid2339(objectP2483.getEid2143());    update(objectP2483); end   -----Inline Attachment Follows----- _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
