1. Re: Business rule task creating issue through JBPM6
salaboy21 May 3, 2014 8:02 AM (in response to lakshjee)There seems to be an issue with a split (gateway node) in your process, can you share the expressions that you use to decide between two (or more branches)?
Regards

lakshjee May 5, 2014 1:27 AM (in response to salaboy21)Hi,
This is what i used for the split node.
return KieFunctions.isTrue(Person.getAdult())==true;
and
return KieFunctions.isTrue(Person.getAdult())==false;
and adult is a boolean data type that i use.
thank you.

swiderski.maciej May 5, 2014 1:53 AM (in response to lakshjee)1 of 1 people found this helpfulthe NPE is most likely caused by Person process variable is not set, make sure that the variable is properly set before it is used on gateway conditions.

lakshjee May 5, 2014 6:37 AM (in response to lakshjee)Thanks all for your guidance..I could be able to run the business rule task. I have done a mistake on Data input and the Output set on the Rule Task.
Now it is working fine.

7. Re: Business rule task creating issue through JBPM6
lakshjee May 19, 2014 8:06 AM (in response to swiderski.maciej)Hi Maciej Swiderski,
I have a four scenario for one rule. Those are as follows,
import org.jbpm.capex.Capex
(1) rule "set as cao_approval" ruleflow-group "capexrule"
no-loop
when $p: Capex(budget>=10000) && Capex(budget<=50000)
then modify($p) { setCao_approval(true); } end
(2) rule "set as coo_approval" ruleflow-group "capexrule"
no-loop
when $p: Capex(budget>=50001) && Capex(budget<=100000)
then modify($p) { setCoo_approval(true); } end
(3) rule "set as gmd_approval" ruleflow-group "capexrule"
no-loop
when $p: Capex(budget>=100001) && Capex(budget<=1000000)
then modify($p) { setGmd_approval(true); } end
(4) rule "" ruleflow-group "capexrule"
no-loop when $p: Capex(budget>=1000001) then end
and the process diagram also attached herewith. But i have no idea how to include fourth rule to the flow. at the gateway split node how to define the condition?
for CAO Approval: return Capex.getCao_approval()==true;
for COO Approval: return Capex.getCoo_approval()==true;
for GMD Approval:return Capex.getGmd_approval()==true;
but Capex(budget>=1000001) how to define it?

mateuszadamiak Jun 9, 2014 8:33 AM (in response to lakshjee)Maybe you need to check your settings of knowledge base/session (look at here https://www.youtube.com/watch?v=TM9cuL_Mfnk). I had similar issue and this was the cause.
