In this blog, I will discuss about Dynamic Participant Step:

<\/span>1. What is the use of Dynamic Participant Step?<\/span>
2. How can we write Custom Dynamic Participant Step?<\/span>
3.How can we use Dynamic Participant Step?<\/span>

<\/span>Use of <\/b>Dynamic<\/b> <\/span>participant step:<\/b>

<\/b>Workflow Dynamic Participant Step is used when the user or a group to perform an activity in that step is selected automatically at run time based on some business logic unlike the user or a group are pre-selected. When we select the dynamic participant step in the workflow, we need to select the respective participant user from the drop down. There are many script\/service available out of the box to select from or we can write our own participant chooser service as well which will be discussed further in this post.

<\/span><\/i>Custom Dynamic Participant Step:<\/b>

<\/b>For crating the Custom Dynamic Participant Step we have to implement ParticipantStepChooser<\/b> in our java class which provide us getParticipant <\/b>method with three parameter Workitem<\/b>, WorkflowSession <\/b>and MetaDataMap<\/b>.<\/p>\n

Register this java class as a component and add some properties as enabled<\/b>, immediate<\/b>, these property indicates-
That this service will be enabled immediate at the time of deployment of your project.<\/span><\/i><\/p>\n

Now register your class as a service with some configurations-
i.e. add a property named as “chooser.label”. <\/b>This property defines a name of your process i.e. in workflow participant chooser step, you are able to see this process in your participant chooser drag drop menu with a name define using this property.<\/p>\n

Our final code will look like this:<\/p>\n

<\/span>})<\/span><\/i>
public class CustomStepForDynamicParticipant<\/span><\/i>
  implements ParticipantStepChooser<\/span><\/i>
{<\/span><\/i>
  private static final Logger logger = LoggerFactory.getLogger(CustomStepForDynamicParticipant.class);<\/span><\/i>
   <\/span><\/i>
  public String getParticipant(WorkItem workitem, WorkflowSession wfSession, MetaDataMap metaDataMap)<\/span><\/i>
    throws WorkflowException<\/span><\/i>
  {<\/span><\/i>
    logger.info(“################ Inside the SampleProcessStepChooserImpl GetParticipant ##########################”);<\/span><\/i>
    String participant = “admin”;<\/span><\/i>
    Workflow workflow = workitem.getWorkflow();<\/span><\/i>
    String initiator = workflow.getInitiator();<\/span><\/i>
    List<HistoryItem> wfHistory = wfSession.getHistory(workflow);<\/span><\/i>
    if (!wfHistory.isEmpty()) {<\/span><\/i>
      participant = initiator;<\/span><\/i>
    } else {<\/span><\/i>
      participant = “admin”;<\/span><\/i>
    }<\/span><\/i>
    logger.info(“####### Participant : ” + participant + ” ##############”);<\/span><\/i>
    return participant;<\/span><\/i>
  }<\/span><\/i>
}<\/span><\/i><\/p>\n
