    Change process variable from domain specific (WorkItemHandler)

    Sam D. Newbie

      Hi,

      I have defined a global process variable VAR_X and a new WorkItemHandler.

      I would like to ask how can set a value to my VAR_X inside my WorkItemHandler and then, of course, impact the global variable?

       

      Thanks

          Hi Sam,

           

          You have to:

          -Define VAR_X as input of the node. Something like this:

          http://dcalca.files.wordpress.com/2011/05/input1.png

          You give it a name to use inside the workItem.

           

          -You can get the variable from work item parameters.

          public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {

                              workItem.getParameter("VAR_X")

          ...

          }

           

           

          - Define VAR_X as output of the node.

          It is similar to the input

           

          - Put this variable in the result map

          Map<String, Object> results = new HashMap<String, Object>();

                                                            results.put("VAR_X", var)

           

          You can see that you are not directly accessing to the global variables.. you have inputs and outputs of each task..
