Hello,

I have a work item with a custom field (of type Contributor) called:

   Requested By:

If for example, this field is set to "John Smith", how can I get the name of the user which is set in the work item via a RTC participant plugin? 

/**
 * Gets the value of a Work Item (Contributor (User)) attribute.
 */
public String getAttributeValue_Contributor(String attributeID) throws TeamRepositoryException
{
   String returnValue = "";
   IAttribute attribute = workItemServer.findAttribute(workItem.getProjectArea(), attributeID, monitor);
   
   Object value = workItem.getValue(attribute);
       
   // ???
   returnValue = contributor.getName();
   return returnValue;
}

Thanks!

Thanks Ralph.

I have it working now :-) 


import com.ibm.team.repository.common.IContributor;
import com.ibm.team.repository.common.IContributorHandle;
import com.ibm.team.repository.service.IRepositoryItemService;

-----------------------------------------------------------
IRepositoryItemService itemService = getService(IRepositoryItemService.class);
-----------------------------------------------------------   

  /**
   * Gets the value of a Work Item (Contributor (User)) attribute.
   *
   */
   public String getAttributeValue_Contributor(String attributeID) throws TeamRepositoryException
   {
      String returnValue = "";
      
      IAttribute attribute = workItemServer.findAttribute(workItem.getProjectArea(), attributeID, monitor);
      
      IContributorHandle contributorHandle = (IContributorHandle) workItem.getValue(attribute);

      IContributor contributor = (IContributor) itemService.fetchItem(contributorHandle, null);

      returnValue = contributor.getName();

      return returnValue;
   }

Do a getValue()
Test if the instance of the object is an IContributorHandle, cast to the IContributorHandle, resolve the contributor from the handle. See https://rsjazz.wordpress.com/2014/05/26/only-owner-can-close-workitem-advisor/

This is true for almost all the values. You have to always cast the data and it is easy enough to look at what it is in a debugging session. Also see https://rsjazz.wordpress.com/2013/03/20/understanding-and-using-the-rtc-java-client-api/
