I am creating a URL like so:

    $this->view->url(array('sort' => array('param1','param2'));

Notice the array of params for 'sort'. This works fine when I am using the standard router. If I use my own router, I always get an error:

    $router->addRoute('controlleralias', new Zend_Controller_Router_Route(
        ':module/mycontrolleralias/:action/*',
        array(
            'module'     => 'mymodule',
            'controller' => 'mycontroller',
            'action'     => 'myaction'
        )
    ));

    urlencode() expects parameter 1 to be string, array given

    #0 [internal function]: __lambda_func(Array)
    #1 /library/Zend/Controller/Router/Route.php(398): urlencode(Array, false, true)
    #2 /library/Zend/Controller/Router/Rewrite.php(441):     Zend_Controller_Router_Route->assemble(Array, NULL, false, true)
    #3 /library/Zend/View/Helper/Url.php(49): Zend_Controller_Router_Rewrite->assemble(Array)

If I do NOT use an array of params, my custom router works fine:

    $this->view->url(array('sort' => 'param1'));

I have concluded that this is a bug in Zend_Controller_Router_Route, that it does not support arrays being used as values when assembling the URLs.
