Zend framework multiple routes for same controller
===

I'm trying to set up Zend pagination on my site so that I can use Paul Irish's jquery infinite scroll plugin, but I'm having trouble with my routes. I currently have these routes set up for my organizer page:

    //Organizer searches
		$route = new Zend_Controller_Router_Route('organizer/index/:filter/:page',
													array('controller'=> 'organizer',
													'action'=> 'index')); 
		$router->addRoute('organizer', $route);
		$route = new Zend_Controller_Router_Route('organizer/index/:filter',
													array('controller'=> 'organizer',
													'action'=> 'index')); 
		$router->addRoute('organizer', $route);

It matches `organizer/index/popular` correctly in this order, but if I put a page number on it the filter suddenly comes up null. If I switch the order, `organizer/index/popular/2` works perfectly fine but `organizer/index/popular` no longer works. I could just only use the more specific route since that's the one I'll need for pagination, but I would like to include both to accommodate users trying to type the url or in case I forget to change the links somewhere in my code. Can I incorporate multiple routes to the same controller with Zend? If so, what am I doing wrong?
