Re: [rules-users] infinite loops with "no-loop true"

Hi all, It seems to me that the no-loop only prevents a rule from triggering itself - and doesn't make the rule only fire once (which is what I'm after) e.g. consider the following two contrived simple rules: rule "addPriorityPrefix" dialect "java" no-loop true when $work : Work (priority >= 200) then modify($work) { setTitle("!!! " + getTitle()); }; end rule "re-assign low priority tasks" dialect "java" no-loop true when $work : Work (priority < -200) then modify($work) { setOwner("nobody"); }; end What I end up with is an infinte loop. Whilst for the simple case I can re-write them like $work : Work (priority >= 200, !title.startWith("!!!")) however with the more complex rules this makes the rules get very complex quickly and less easy to write. Is there a way to prevent these loops - have I misunderstood or do you really need to check everything in the rule that you may set? How would you do the banking interest example? rule "interest calculation" no-loop when $account : Account( ) then modify($account) { setBalance((long)($account.getBalance() * 1.01) ) }; end if there was another rule that if you where a gold customer and payed in > $500 the previous month then you get $4 bonus? rule "gold bonus" no-loop when $account : Account(type="gold", previousMonthDeposit > 500 ) then modify($account) { setBalance((long)($account.getBalance() + 4) ) }; end Regards, /James ************************************************************************************** This message is confidential and intended only for the addressee.
