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
-------------------------------
package ext;
import wt.epm.EPMDocument;
import wt.events.KeyedEvent;
import wt.fc.PersistenceHelper;
import wt.fc.QueryResult;
import wt.fc.ReferenceFactory;
import wt.fc.WTReference;
import wt.part.WTPart;
import wt.query.QuerySpec;
import wt.query.SearchCondition;
import wt.services.ServiceEventListenerAdapter;
import wt.util.WTException;
import wt.util.WTPropertyVetoException;
import wt.vc.VersionControlServiceEvent;
public class VersionEventListenerAdapter extends ServiceEventListenerAdapter {
public VersionEventListenerAdapter(String serviceId) {
super(serviceId);
}
public void notifyVetoableEvent(Object event) throws WTException, WTPropertyVetoException {
if (!(event instanceof KeyedEvent)) {
return;
}
Object target = ((KeyedEvent) event).getEventTarget();
Object eventType = ((KeyedEvent) event).getEventType();
System.out.println("FROM @@@@@@@@@ Target >>>>> "+target);
System.out.println("FROM @@@@@@@@@ eventType >>>>> "+eventType);
ReferenceFactory refFactory = new ReferenceFactory();
WTReference ref = refFactory.getReference(target.toString());
if (eventType.equals(VersionControlServiceEvent.NEW_VERSION))
{
/** Call your business code here
example : yourMethod(target);
**/
System.out.println(">>>>>>>> INSIDE EVENT TYPE >>>> ");
if(target instanceof WTPart){
WTPart wtp = (WTPart)ref.getObject();
System.out.println("Name >> "+wtp.getName());
System.out.println("Number >> "+wtp.getNumber());
System.out.println("Created By >> "+wtp.getCreatorFullName());
System.out.println("Creation Time >> "+wtp.getCreateTimestamp());
System.out.println("Time >>> "+System.currentTimeMillis());
System.out.println(" VERSION >> "+wtp.getVersionIdentifier().getValue()+"."+wtp.getIterationIdentifier().getValue());
System.out.println("======= =================");
// below code to fetch attribute GOB_WEIGHT
com.ptc.core.lwc.server.LWCNormalizedObject obj = new com.ptc.core.lwc.server.LWCNormalizedObject(wtp, null,
java.util.Locale.US, new com.ptc.core.meta.common.DisplayOperationIdentifier());
obj.load("GOB_WEIGHT");
java.lang.String string_value = (java.lang.String) obj.get("GOB_WEIGHT");
System.out.println("Soft attibute value : " + string_value);
}
}
}
}
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.

Vivek
