Notice: Undefined property: stdClass::$detailed_question in faq_form() (line 231

I can't reproduce this. Is it still a problem?

No update to my question, so closing this issue. Feel free to reopen if the problem is still occurring.

Have the same problem. Even have the same issue when running simpletest:

Could it be something with the server setup?
Running Apache/2.2.20 (Ubuntu 11.10), PHP Version 5.3.6-13ubuntu3.6 and with clean urls enabled.

I can't reproduce with the latest version of the faq module (6.x-1.13) with PHP 5.2.5 and Apache 2. Can you try it with the latest version?

Attached is a devel- snapshot of the parameters passed to the faq_form function when error occurs. Hope this might shed some light on the issue. Will try and investigate a little more on what is happening.

At line 354 in faq.module the following hook is defined:

/**
 * Implements hook_content_extra_fields().
 */
function faq_content_extra_fields($type_name) {
  $extras = array();

  if ($type_name == 'faq') {
    $extras['detailed_question'] = array(
      'label' => t('Detailed question'),
      'description' => t('FAQ detailed question field'),
      'weight' => 10,
    );
  }

  return $extras;
}

I cannot seem to find where the hook is called. There are no hook_content_extra_fields() in the core documentation
http://api.drupal.org/api/search/6/hook_content_extra_fields

A suggested fix (although I'm not sure if that only fixes the symptom rather than the root cause) is to replace the reference to
'#default_value' => $node->detailed_question,
with something like
'#default_value' => isset($node->detailed_question)?$node->detailed_question:'',
Patch attached

hook_content_extra_fields() is a CCK hook. It declares the field to CCK so it can be re-ordered on the 'display fields' page.

I've committed the patch. I'm not sure why that field is undeclared but we might as well fix the error. Thanks!

Thank you for the explanation. Did not check for the CCK hooks :-)
Have come across another related issue I suppose:
Notice: Undefined property: stdClass::$revision in faq_update() (line 262 of /var/www/d6/sites/all/modules/faq/faq.module).
Create similar fix on this one too?

Done!
