GWT Integration Error

The gwt-integration-error
is a library that helps to deal with error and exception management.
The problem: without configuring anything, the errors are simply logged but no message is shown to the client. A way to inform the client that something wrong happened should be provided.
The solution: Subclass and use BaseUncaughtExceptionHandler
.
For example, there is the readily-available DialogBoxUncaughtExceptionHandler
that shows a simple dialog box when an error happens.
You need to configure it in your module loading method:
public void onModuleLoad() {
GWT.setUncaughtExceptionHandler(new DialogBoxUncaughtExceptionHandler());
...
}
