Problem
You want to handle errors ONLY if nothing else handles them.
Solution
Use the App::pushError() method.
This will add your handler to the bottom of the stack instead of the top of the stack.
App::pushError(function($exception)
{
die('ERROR: '.$exception->getMessage());
});
Discussion
This is exactly like App::error().
Except the handler is placed on the bottom of the stack instead of the top. See Registering an Error Handler.
