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.
