anyone guide me how to access processinstance in split constraints?

[rickylkl]

Dear all,

rule "Example validation rule"
    ruleflow-group "validate"

    when
        processInstance : WorkflowProcessInstance()
    then
        processInstance.setVariable("isValid", new Boolean(false));
end

that's wt i know to access processInstance in rule flow , drl file .

But how do i get the isValid variable in SPLIT GATEWAY CONSTRAINTS ??

THanks & Regards

you should do something like the following if you are writing a Java expression.

return kcontext.getKnowledgeRuntime().getProcessInstance(<id>).getVariable("isValid");

If you wanna write a rule expression it will be in the same way as you showed before:

WorkflowProcessInstance(variables["isValid"] == <true|false>)

Cheers

Hi Salatino ,

     Thanks for the reply, may i ask a bit more?

     1.     How can i know the processInstance id in split constratins ?

     2.     By the way, when i try this - WorkflowProcessInstance(variables["isValid"] == true), it shows below exception, any idea ?

             unable to resolve method using strict-mode: org.drools.runtime.process.WorkflowProcessInstance.variables

             [Near : {... variables["isValid"] == true ....}]

     Thanks & Regards
