Thread: Accumulate x No-loop
Accumulate x No-loop

United States		 2008-05-02 15:45:01 
Hi
When I use accumulate and update, no-loop is ignored and the
rule is
recursive.
Why?

The Rule:

rule "Nota final das questoes"
	no-loop true
	when

		questionarioResposta : QuestionarioResposta()
		$result : Number() from
accumulate(QuestaoResposta($nota:nota,$peso:questao.questaoP
eso.peso) 
										   from
questionarioResposta.getQuestoesResposta(), 
										   sum($nota * (Double)$peso))
										   
		 $resultFinal : Number() from
accumulate(QuestaoResposta($nota:nota,$peso:questao.questaoP
eso.peso) 
										   from
questionarioResposta.getQuestoesResposta(), 
										   sum( $peso )) 
										   				 
	then
		System.out.println($result.doubleValue() /
$resultFinal.doubleValue()); 
		questionarioResposta.setNotaFinal($result.doubleValue() /
$resultFinal.doubleValue());
		update( questionarioResposta );
end

Sorry, my code is ugly in last email...
This is more clean:

rule "The Rule"
    no-loop true
    when

        questionarioResposta : QuestionarioResposta()

         $resultFinal : Number() from 
accumulate(QuestaoResposta($peso:questao.questaoPeso.peso)
                                           from 
questionarioResposta.getQuestoesResposta(),
                                           sum( $peso ))
    then
        System.out.println($resultFinal);
        update( questionarioResposta );
end

This is a recursive and no-loop is ignored.
Who knows why this?

Thanks

    Hi Alessandro, just saw your e-mail and answered to you, but basically no-loop will not work for cases like this.
    Either specify your constraints in a way they prevent the loop or use lock-on-active.


rule "Nota final das questoes"

   when

       $qr : QuestionarioResposta( $nf : notaFinal )

   ;    $result : Number( this != $nf )

   ;           ;       from accumulate( 
QuestaoResposta($nota:nota,$peso:questao.questaoPeso.peso)

      ;           ;           ;           ;   from $qr.questoesResposta,

       ;           ;           ;           ;  sum( $nota * (Double)$peso ) 
)     ;  
      
   then

       modify( $qr ) {

   ;           setNotaFinal($result)

       }

end

    Hope it helps.
        Edson
