In the Zend Framework, the Paginator View Helper looks by default for the partial specified under the views/scripts directory for the current module. If the partial is defined in one module (e.g. default) and used in another (e.g. admin), the module where it is located needs to be specified. For instance, you would use the following when rendering a pagination control defined in the default module from another module:
$this->paginationControl($this->paginator, 'sliding', array('pagination_control.phtml', 'default'));
Note that rather than just specifying the partial file name as a string in the third parameter, we pass an array with the partial file name as the first entry, and module name as the second.
