Conflicts with Openlayers

I'm using this module and there is a conflict with Openlayers.
If I've an Openlayers Map with popup and I click a popup, this click "clones" every input interested by hint.
This is the code I use:

function alterator_form_alter(&$form, &$form_state, $form_id) {
  if ($form['#id'] == 'views-exposed-form-ricerca-ricerca-page') {
    $form['chiave']['#hint'] = t('Search on site');    
  }
}

The problem there is also with the user-login block, not interested by my custom module.
If I disable the module, everything is ok.
