I'm figuring out why this simple script is not working:

```
jQuery.noConflict();
jQuery(document).ready(function() {
    jQuery('.next_button a').trigger('click');
});

```

`noConflict` is necessary because I also load prototype/scriptaculous in this page.

If I replace `.trigger('click')` with another function (es: `.css(...)` this works well. Only triggering seems to go broken.
