In this situation you need to inject Solar_Form with the correct
filter instance. For that filter instance you need to tell where to
look for filters.

So

    $filter = Solar::factory('Solar_Filter');

    $filter->addFilterClass('Vendor_Filter');

    $form = Solar::factory('Solar_Form', array('filter' => $filter));
    // ...

Hope that helps.
