Hi all,


    I'm writing a rule that analyze a variable in my process, and this variable is taken in consideration to fire a rule. So I did something very simple using the from conditional element in the left hand side.


rule "Test"
          ruleflow-group "test"
          when
                    $processInstance : WorkflowProcessInstance()
                    $str : String() from (String)$processInstance.getVariable("strValue");
          then 
                    System.out.println("str: " + $str);
end
 


     My doubt is that when I have this variable "strValue" started as a parameter when I start the process everything works fine but when I have it initialized using a Script Task node before my Rule Task node, the rule isn't fired. 

kcontext.setVariable("strValue", "test value");


     I can check that the value is set if I use it in the right hand side (without from) or getting the variable value from the java code who started the process.

    Any guess about this behavior?

Thanks!
