Hi!
in my process there is a rule-task that set some process variable... for example, this is one rule:

rule "no result"
          ruleflow-group "rules"
          when

                    $process: WorkflowProcessInstance()
                    $c: CostFlight(cost == "0") 

          then 

           System.out.println("Nosolution avaible!");
           $process.setVariable("result","no_result");

end

and at this point I haven't any problem. If I use a diverging gateway ( XOR) with 2 possible way, I must write 2 constraint like this:

(to node NO_RESULT)
 org.drools.runtime.process.WorkflowProcessInstance process = (org.drools.runtime.process.WorkflowProcessInstance)kcontext.getProcessInstance();     
 return "no_result".equals(process.getVariable("result"));

(to node RESULT)
 org.drools.runtime.process.WorkflowProcessInstance process = (org.drools.runtime.process.WorkflowProcessInstance)kcontext.getProcessInstance();     
 return "ok".equals(process.getVariable("result"));



but when I try to launch it, I have this ERROR:
