Class

editableviews_handler_field_entity_metadata_property

Field handler for editing an entity metadata property.

Code

function edit_form($entity_type, $entity, &$element, &$form_state) {

  // Something weird in Views admin UI causes us to come here (because the
  // style plugin gets rendered) without the options set on this handler. This
  // then causes an AJAX error because further down we access a metadata
  // wrapper with no property. I have no time to go chasing this right now, so
  // for now, just bail here if we're not properly set up. Doing this appears
  // to have no adverse or visible side effects.
  if (empty($this->options['property'])) {
    return;
  }

  // this once.

  }

    // show a select form element of options.
    $this
      ->edit_form_element_select($element, $form_state, $wrapper);
  }

    // This is just a best guess.
