Disable widget when #disabled = TRUE in the form using FAPI

I needed to apply this configuration in the form item:

'tags' => array(
  '#type' => 'autocomplete_deluxe',
  '#title' => t('Add a minimum of 5 labels in your image'),
  '#prefix' => '<div class="image-tags-field">',
  '#suffix' => '</div>',
  '#size' => 60,
  '#limit' => 10,
  '#min_length' => 0,
  '#use_synonyms' => 0,
  '#delimiter' => '',
  '#not_found_message' => "The term '@term' will be added.",
  '#element_validate' => array('sto_collection_tags_validate'),
  '#multiple' => TRUE,
  '#autocomplete_deluxe_path' => url('autocomplete_deluxe/taxonomy/field_tags', array('absolute' => TRUE)),
  '#default_value' => $tags,
  '#disabled' => !$incomplete,
),

Where $incomplete refers to a status node, but basically I wanted to set to TRUE in some cases. The input field is disabled but no the rest of items and controls.

So I've made some changes and the #disabled option is used by the autocomplete widget to disable the remove tags event and search event.

I apologize I don't know how to create I patch form the current version so I'll leave the following lines of code:

In autocomplete_deluxe.module in line 278 I've made this change:

  $js_settings['autocomplete_deluxe'][$html_id] = array(
    'input_id' => $html_id,
    'multiple' => $element['#multiple'],
    'required' => $element['#required'],
    'limit' => isset($element['#limit']) ? $element['#limit'] : 10,
    'min_length' => isset($element['#min_length']) ? $element['#min_length'] : 0,
    'use_synonyms' => isset($element['#use_synonyms']) ? $element['#use_synonyms'] : 0,
    'delimiter' => isset($element['#delimiter']) ? $element['#delimiter'] : '',
    'not_found_message' => isset($element['#not_found_message']) ? $element['#not_found_message'] : "The term '@term' will be added.",
    'disabled' => isset($element['#disabled'])? $element['#disabled'] : false,
  );

In autocomplete_deluxe.js in line 310 I've made this change:

if (!self.widget.disabled) self.remove(item);

And in autocomplete_deluxe.js in line 379 I've wrapped the binding setup in the following conditional:

   //Binding events
    if (!this.disabled) {
      parent.mouseup(function() {
        jqObject.autocomplete('search', '');
        ....
        ....

      jqObject.keyup(function (event) {
        if (clear) {
          // Trigger the search, so it display the values for an empty string.
          jqObject.autocomplete('search', '');
          jqObject.val('');
          clear = false;
          // Return false to prevent entering the last character.
          return false;
        }
      });
    }

I hope this can help someone or somehow to improve this excellent module!

Thanks!
