Facing issue while getting Business Attribute of a WTpart by using NEW_VERSION event

Hi All,

My requirement -> fetch a Business Attributes of WTPart, just after the WTPart creation.

for this purpose, i am using this event " VersionControlServiceEvent.NEW_VERSION ".

i am able to get part Name,number, creator, timestamp etc here, but when i try to fetch Business Attributes, its gives value null, even there a business attribute present with valid values.

Here is My code, Please let me know where i am doing wrong ?

Any help will be great !!

1. VersionEventListenerAdapter.java

2. MStandardListenerService.java

package ext;


import wt.services.ManagerException;
import wt.services.StandardManager;
import wt.util.WTException;
import wt.vc.VersionControlServiceEvent;


public class MStandardListenerService extends StandardManager implements MListenerServiceInterface {


  private static final long serialVersionUID = 1L;  protected synchronized void performStartupProcess() throws ManagerException {     VersionEventListenerAdapter versionEventListenerAdapter = new VersionEventListenerAdapter(getName());     getManagerService().addEventListener(versionEventListenerAdapter, VersionControlServiceEvent.generateEventKey(VersionControlServiceEvent.NEW_VERSION));     getManagerService().addEventListener(versionEventListenerAdapter, VersionControlServiceEvent.generateEventKey(VersionControlServiceEvent.PRE_NEW_VERSION));     getManagerService().addEventListener(versionEventListenerAdapter, VersionControlServiceEvent.generateEventKey(VersionControlServiceEvent.POST_INSERT_ITERATION));     getManagerService().addEventListener(versionEventListenerAdapter, VersionControlServiceEvent.generateEventKey(VersionControlServiceEvent.POST_ROLLUP));     getManagerService().addEventListener(versionEventListenerAdapter, VersionControlServiceEvent.generateEventKey(VersionControlServiceEvent.POST_SUPERSEDE));      }  public static MStandardListenerService newMStandardListenerService() throws WTException {     MStandardListenerService instance = new MStandardListenerService();     instance.initialize();     return instance;  }
}

Please check and suggest me.
