Hi
I am trying to capture the a rollback event from the dataContext and I have
tried variation of the code below but nothing seems to work. My event
handlers never get called. I would have used the DataObject jandlers but
they don't support rollBack.
Can anyone see what I am doing wrong? Many thnaks for your help.
public class SomeDataObject() extends MyDataObject {
public static DataContextTransactionEventListener
dataContextTransactionListener = new DataContextTransactionEventListener() {
public void dataContextDidCommit(DataContextEvent event) {
System.out.println("*** xxSomething changed! DID_COMMIT ***");
}
public void dataContextDidRollback(DataContextEvent event) {
System.out.println("*** xxSomething changed! ROLLEDBACK ***");
}
public void dataContextWillCommit(DataContextEvent event) {
System.out.println("*** xxSomething changed! WILL_COMMIT
***");
}
};
public static DataChannelListener dataChannelListener = new
DataChannelListener() {
public void graphChanged(GraphEvent event) {
System.out.println("*** Something changed! DID_COMMIT ***");
}
public void graphFlushed(GraphEvent event) {
System.out.println("*** Something changed! ROLLEDBACK ***");
}
public void graphRolledback(GraphEvent event) {
System.out.println("*** Something changed! WILL_COMMIT ***");
}
};
@Override
public void fetchFinished() {
super.fetchFinished();
System.out.println("*** FETCH FINISHED! ***" + this.toString());
// this.getDataContext() is DataContext.getThreadedContext()
this.getDataContext().setTransactionEventsEnabled(true);
DataContext.setTransactionEventsEnabledDefault(true);
EventUtil.listenForChannelEvents(this.getDataContext().getChannel(),
dataChannelListener);
EventManager.getDefaultManager
().addListener(dataContextTransactionListener,"dataContextDidRollback",
DataContextEvent.class,DataContext.DID_ROLLBACK, null);
}
....more methods
}
