Cancel GWT RequestFactory request

Question

Is there a way to cancel/abort request factory requests? Using GWT 2.3

Answer 1

There is no way to cancel a request after the fire() method has been called. Consider building a custom Receiver base class such as the following:

public abstract class CancelableReceiver<V> extends Receiver<V> {
  private boolean canceled;

  public void cancel() {
    canceled = true;
  }

  @Override
  public final void onSuccess(V response) {
    if (!canceled) {
      doOnSuccess(response);
    }
  }

  protected abstract void doOnSuccess(V response);
}

The pattern can be repeated for other methods in the Receiver type.
