Do you have an import statement for importing
TipoCaracteristica?
I see you are already using TipoMolde.CABELO which I
assume is another public static variable in the
TipoMolde class.
If none of these work can you post your drl file?

About the problem... I solved it.
But now I'm getting this error when I use a static
property in the rules:

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.
