Approve Engineering Change Request is a multiple user task, there are three vote options: Approve, Research_Required and Reject.

Requirements: If user votes on “Research_Required” and “Reject”, then comment is mandatory, currently we don’t have check for this.

Technical solution Options

1. Use the code in Complete transition, but his only works for Single user tasks.
2. Use java script check thru UI
3. Create a class extends StandardNmWorkItemService service class

Below is how I achieve this using #3.

First, add this service to wt.properties

wt.services.service.10041=com.ptc.netmarkets.work.NmWorkItemService/MyNmWorkitemService

Below is the code of the service.

package ext.hhi.services;

import java.util.HashMap;
import java.util.Iterator;

import wt.fc.ObjectReference;
import wt.fc.Persistable;
import wt.method.RemoteMethodServer;
import wt.util.WTException;
import wt.workflow.engine.Wf
