im using
- RichFaces 4.5.1.Final
- Weld 2.2.8.Final
- Mojarra 2.1.29
- JSF 2.1
The problem is when im starting to use template with Facelets and an exception is thrown in this case obviously NullPointerException but if you see the stacktrace is wrapping the exception into another exception and i cant see the real cause of the problem, the original exception. Is important to say that if i coment the NPE code works perfectly. Any ideas that was causing the issue, Facelets, JSF or Weld. this happen with all exception
I have this structure:
Controller
@Named(value="productoController")
@ConversationScoped
public class ProductoController {
public void alta(){
String test = null;
//Throw NPE
test.concat("");
}
}

Thanks Ignacio
Response for User BalusC, i attached the screen and receive the same result with FullAjaxExceptionHandler.
I saw this in the console maybe you can use (this doesnt reflect in the view):
