Yes I'm Brazilian....
I need to improve my english I now hehehe

About the problem... I solved it.

But now I'm getting this error when I use a static property in the rules:

Exception in thread "AWT-EventQueue-0" org.drools.RuntimeDroolsException: Exception executing predicate org.drools.base.mvel.MVELPredicateExpression@916f80

Example:

Property :
public class TipoCaracteristica implements java.io.Serializable{
.
.

    public static int CABELO_TOTALMENTE_CALVO = 37;
.
.
.
}

rule:

rule "CABELO_TOTALMENTE_CALVO resposta nao / Chama Tipo de Cabelo"
salience 90
    when
        e : Especialista(perguntado == false)
        Especialista( $retrato : retratoUser)
        Retrato($lstCaracRetrato : lstCarac) from $retrato
        Retrato($lstMolde : lstMolde) from $retrato
        Molde(tipoMolde.codTipMolde == TipoMolde.CABELO && $lstCaracMolde: lstCarac) from $lstMolde
        //CABELO_TIPO = 10
        eval(naoPerguntou($lstCaracMolde, 10))
        //CABELO_TOTALMENTE_CALVO = 37 e RESPOSTA_SIM = 154
        Caracteristica(tipCarac.codTipCarac == TipoCaracteristica.CABELO_TOTALMENTE_CALVO && valor.codValor == 154) from $lstCaracMolde
    then
        buscarMontarPergunta(e,Pergunta.CABELO_TIPO,Especialista.CABELO);
        e.perguntado = true;
        update(e);
end

I get some statics properties like "TipoMolde.CABELO" without errors, but I can't use the properties from this class (TipoCaracteristica). Did you know why?
If I use de value like this " valor.codValor == 154", I have no problem.

    Anderson,

    What is the error? Can you provide a self contained example?
    Using the "from CE" as showed before works.

    BTW, are you Brazilian? Your name sounds like a Brazilian name.

How can I test all elements of the list?
Can I need to use something like "for (int i.....)"?

I'm trying to do that but it is not working...

"Caracteristica( codCarac != 0 ) from $caracList"

My test:

        e : Especialista (perguntado == false)
        Especialista( $moldeList : retratoUser.lstMolde )
        Molde( tipoMolde == TipoMolde.CABELO) from $moldeList

When the property "tipoMolde == TipoMolde.CABELO" the rule must to be fired. The List $moldeList has 5 elements.

any idea?

2007/10/3, Edson Tirelli < tirelli@post.com>:
Use the "from" CE:

rule "This rule will fire once for each Caracteristica whose codCarac is != 0"
when
    Especialista( $caracList : retratoUser.lstCarac )
    Caracteristica( codCarac != 0 ) from $caracList
then
    ...
end

   []s

If I want to test for all ith element,

Like this

rule "Test"

    when
        e : Especialista(retratoUser.lstCarac.get(i).codCarac != 0)
    then
        System.out.println ("test");

end

what should I do

   You can't explicitly call methods in the field name. Use MVEL special notation for lists:

e : Especialista(retratoUser.lstCarac[0].codCarac != 0)

Hi everyone,

I'm trying to use a java.util.List like this:

rule "Test"

    when
        e : Especialista(retratoUser.lstCarac.get(0).codCarac != 0)
    then
        System.out.println ("test");

end

The property lstCarac is a java.util.List<Caracteristica>. I'm getting this error :

org.drools.rule.InvalidRulePackage: [18,44]: unknown:18:44 Unexpected token '0'[18,46]: unknown:18:46 Unexpected token '.'
    at org.drools.rule.Package.checkValidity(Package.java:419)

Someone knows what i have to do to fix the problem??
