I think what Evaldas means is that an error (template not found, etc) 
in the View rendering stage will not be caught by the method in the 
Cookbook.

I am away from my code at the moment, but IIRC the trick is to check 
$c->error AFTER you forward to MyApp::V::TT (or after the RenderView 
action) and then setup your error.tt template and forward to the view 
again.

If that doesn't make sense I can provide a code example later.

Best,
Brian
