Something like this...

sub render : ActionClass('RenderView') { }

sub end : Private {
	my ( $self, $c ) = @_;

	$c->forward( 'render' );

	if ( my @errors = @{ $c->errors } ) {
		$c->response->content_type( 'text/html' );
		$c->response->status( 500 );
		$c->response->body( qq{
			<html>
			<head>
			<title>Error!</title>
			</head>
			<body>
				<h1>Oh no! An Error!</h1>
		} . ( map { "<p>$_</p>" } @errors ) . qq{
			</body>
			</html>
		} );
	}
}
