Hello everyone,

Confirming this post I have spot three issues for Webform Simplenews Component module.

1) The description text isn't show in the form.
2) The newsletter_email field cannot be set to unique (like the webform email field).
3) Webform Validation module doesn't identify newsletter_email component and no validation rules can be applied for this component.

The first issue can be easily fixed, making the following additions in the webform.simplenews.inc file:
- in the function _webform_defaults_newsletter_email() 

function _webform_defaults_newsletter_email() {
  return array(
    'name' => '',
    'form_key' => NULL,
    'pid' => 0,
    'weight' => 0,
    'value' => '',
    'user_email' => 1,
    'mandatory' => 0,
    'email' => 1,
    'extra' => array(
      'width' => '',
+    'description' => '',	  		
      'attributes' => array(),
      'news_vid' => 0,
      'action' => '',
    ),
  );
}

- in the function _webform_render_newsletter_email($component, $value = NULL)

function _webform_render_newsletter_email($component, $value = NULL) {
...
  $element = array(
    '#title'             => htmlspecialchars($component['name'], ENT_QUOTES),
    '#required'          => $component['mandatory'],
    '#weight'            => $component['weight'],
+  '#description' => $filter ? _webform_filter_descriptions($component['extra']['description'], $node) : $component['extra']['description'],			
    '#prefix'            => '<div class="webform-component-'. $component['type'] .'" id="webform-component-'. $component['form_key'] .'">',
    '#suffix'            => '</div>',
    '#webform_component' => $component,
    '#theme'             => 'webform_newsletter_email',
    '#element_validate'  => array('_webform_validate_newsletter_email'),
  );
...
}

I tried to fix the second one (unique) by making similar additions but it seems that the function which controls unique validation cannot be loaded from this file.

I have no idea with regards to the third issue, but if it is solved it is possible to add unique rule for newsletter_email components using Webform Validation module.
Of course you can always use the Webform PHP module in order to add rules for newsletter_email components (already successfully tested).

Any ideas would help.

Thank you for your time.

Best regards
John
