    JBPM Change/Update Variable Value

    Can Isal Newbie

      Hello,

       

      I have built an Inventory Tracking Process Project using JBPM Eclipse and in jbpm-console all the nodes in the process seem to be running ok. However, in the start process called "Prepare Order", I have many variables one is called "customerName". When I give a value for this variable and click "Save and Close" it works fine and saves the value for "customerName". After Start Process, I have a Task Node called "Approve Order" and to approve the

      order the actor should see "customerName" variable's value. All is working fine until this point and in "Approve Order" node, actor can see the "customerName" variable value. However, when I try to change the value of "customerName" from something like "Chris" to "Christina" and click "Save and Close". The value never updates and keeps the value in the Start Process as "Chris". Is it possible to change/update value of a variable?

       

      Please help me with this, it should be easy but I can't find any solution.

       

      Thanks

          Could you please share your process definition? Are you sure that you are mapping the output variable containing the new value in the second task into a process variable?

            By the way I am using jbpm-jpdl-3.2.G.A. So Start State "Siparis hazirlama" has a variable musteriAdi and Task Node "Siparis onaylandi mi?" has the same variable but can't change its value.

             

            Here is processdefinition.xml.

             

            <?xml version="1.0" encoding="UTF-8"?>

              Anybody knows the answer to this question. How to change the variable value on different nodes? Variable only gets the value on the first node that it is defined, after that it is not possible to change its value.
