Re: JESS: How to stop firing rules (again)

Hi Jason,

thanks for your answer, one of errors I get is throwed when I try to assert the next fact: (MAIN::call-method (id "13") (template call-method) (parent-method-id "9") (parent-id "12") (params "10")).

Error Message is:

Jess reported an error in routine factid

I get similar errors messages sometimes (these errors are not shown always) when I modify facts. I modify and add facs from the next java methods:

// To assert facts

public static void assertFact(Fact f){
  try {

   // This call is not outstanding
   f.setSlotValue("id",new Value(FactIdProvider.INSTANCE.getNewFactId(),RU.STRING));


     engine.assertFact(f);

     facts.addFact(f);

  } catch (JessException e) {

   System.err.println(
    "Se produjo un error afirmando el hecho: "
     + f.toString());
   e.printStackTrace();
  }
}

// To modify slot values

public static void setSlotValue(
  int factId,
  String slotName,
  String slotValue) {
  try {
   // Si esta vacio se establece a 'espacio en blanco'
   if (slotValue.equals("")){
    slotValue = " ";

   }

   // Se ejecuta la sentencia
   engine.executeCommand(
       "(modify " + factId + " (" + slotName + " " + slotValue + "))");


  } catch (JessException e) {
   System.err.println(
    "FactID como int: Se ha producido un error estableciendo el valor del slot "
     + slotName
     + " del hecho con id "
     + factId
     + " al valor "
     + slotValue);
   e.printStackTrace();
  }
}

I hope this source code to help you to understand what I'm trying to do, thanks againg,

Felix.

Hi all,

I posted the same question some weeks ago. I thought at that time that my problem was fixed... but it seems now that I was wrong! So I will explain it again...

Hi Flelix,

An ounce of source code is worth a pound of explanation. :-D

Please post your actual code, and I bet the group can help you much faster.

Cheers,
