What trouble? What doesn't work, what happens, what do you want to happen?
First issue I see is that you render the pagination in the controller. This will produce HTML, which you have to pass to the view using set_safe(), otherwise it will be encoded and displayed as text.
I wouldn't know why it would not route to that. You have a controller called "Controller_Yrm", and it has a method called "action_other"? It is called at all? Or do you see your 404 page?
