How to get participant step dialog values to process step

HI Team,

Is it possible to get dynamic participant step dialog values to customized process step, if possible could you please guide me how to proceed.

i am getting null in value1:

my code is :

DynamicParticipant :

public class MyDynamicParticipant implements ParticipantStepChooser{

   public String getParticipant(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap args) throws WorkflowException {

        WorkflowData workflowData = workItem.getWorkflowData();

        String myID = args.get("COMMENT").toString();

      LoggerUtil.infoLog(this.getClass(), "####  Reading Dialog information ... {}", myID); 

      workItem.getWorkflowData().getMetaDataMap().put("MyIDkey", myID);    

    }

}

Process :

public class CustomStep implements WorkflowProcess{

@Override

public void execute(WorkItem item, WorkflowSession wfsession,MetaDataMap args) throws WorkflowException {

try

{

       String value1 = item.getWorkflowData().getMetaDataMap().get("MyIDkey", java.lang.String.class);

     LoggerUtil.infoLog(this.getClass(), "current page path information ... {}", value1);

    }catch (Exception e)

    {

    LoggerUtil.applicationErrorLog(this.getClass(), "****** An Exception occurred while executing getToggleButtons() ::  {} ", e);

    }

}

  }
