Creating a Scripted Transition Processor

A transition processor is used in the dataflow engine to manipulate the process entity or objects belonging to it when it reaches a configured node or edge. You can attach such a processor to the following components:

• node:
  • onEntered list property
  • onLeft list property
• edge:
  • onTransit list property

For more information about dataflow engine, see Dataflow Engine.

Creating a Scripted Transition Processor in Control Center

1. In Control Center, navigate to Transition Processors entry point.

2. On the Action Bar, click New and select ScriptedTransitionProcessor. A new modal window opens.

3. In the modal window, provide an externalId, name, and click the Assign link next to the script label. A new modal window opens.

4. Select the script type which you want to code in and click Finish. The script properties window opens.

5. In the script properties window, there is only one property: source. Paste or write your custom script there, for example:

   if($.getProcess().getProcessEntity().getProcessStepNumber()=="3"){
     $.getProcess().getProcessEntity().setProcessStepNumber("4");
     $.continueWithState("nextStep");
   } else {
    $.continueWithState("error");
   }
   

   For more information on the available functionality and syntax of a script, see Scripting.

6. Apply your changes. You can now assign your new scripted transition processor to a node or an edge in the process designer.
