[rules-users] Problem in update() method

[Greg Barton]

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.)

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
