[rules-users] Problems with int and Integer inside Return Value and Predicate Expression

[Felipe Piccolini]

The Solicitud object has sumaMontoLCG and sumaMontoGarantia atts as  
int (primitives).

Im using 3.0.6 and java 1.5

I have this simple rule:

rule "montos maximos y minimos"
	salience 888
	when
		a: Actor(tipo :tipoActor == Actor.JefeOficina, max: limiteMaximo,  
min: limiteMinimo)
		s: Solicitud( sumaLCG: sumaMontoLCG < max, sumaGTIA:  
sumaMontoGarantia -> ( (sumaLCG.intValue() - sumaGTIA.intValue()) <  
min.intValue()) )
	then
		System.out.println("Suma LCG:"+sumaLCG);
		System.out.println("Actor lim max:"+max);
		System.out.println("Actor tipo:"+tipo);
end

Fire the rule shows me this error:
org.drools.RuntimeDroolsException:  
java.lang.ArrayIndexOutOfBoundsException: 1

	... 17 more


When I change the column to:
	s: Solicitud( sumaLCG: sumaMontoLCG < max, sumaGTIA:  
sumaMontoGarantia -> ( (sumaLCG - sumaGTIA) < min) )

its shows this error:
org.drools.rule.InvalidRulePackage: Rule Compilation error The  
operator - is undefined for the argument type(s) java.lang.Integer,  
java.lang.Integer

	at org.drools.rule.Package.checkValidity(Unknown Source)

(SolcredRulesPoC.java:60)
	at cl.bluesoft.jbrules.loader.solcred.SolcredRulesPoC.main 
(SolcredRulesPoC.java:36)

This happens in a predicate or in a value expression, so I cant use  
this formula... What is wrong?

Thx.
