public interface AlertCallback extends BrowserAsyncCallback<AlertCallback.Params,AlertCallback.Action>
This callback is invoked when JavaScript alert dialog should be displayed. In this callback you can display standard Java modal dialog with the message that you can get from AlertCallback.Params.

Use the AlertCallback.Action.ok() method to tell browser that the alert dialog was closed.

Please note that it is not necessary to display a dialog in this callback.

If the callback throws an exception, the AlertCallback.Action.ok() method will be invoked.
