I have a pollfield CCK in my forum. On saving a forum poll, I get the following returned on the screen and nothing else:

Is this an ajax return?

Core poll is disabled.
ajax_poll is installed, but not enabled.

It doesn't happen if a forum post is created without a pollfield.

Sorry, this may be a duplicate of http://drupal.org/node/591696

I'm not 100% sure about terminology, but is what I'm seeing JSON? Is so, it occurred after a form error and adding a further option, so do delete us duplicate if this is the case.

P.S. Also just noticed that the poll is actually created okay.

Okay, solved for me. It is down to the above AHAH error, but here's a specific solution for pollfield used within advanced_forum.

Here's the full solution ('cos I hate seeing solutions that say "you need this code", that don't tell you where to put it). Create yourself a helper module under /sites/all/module/ where all your other contrib modules are (you just need a helper.info and helper.module file - Google for Drupal module creation or just copy from another module you've already downloaded). Then create a new hook_form_alter function in your helper.module file to deal with this specific problem. Naturally your module doesn't need to be called "helper".

function helper_form_alter(&$form, &$form_state, $form_id) {
  if(module_exists('pollfield') && ($form_id == 'forum_node_form')) {
    $form['#action'] = '';
  }
}

Setting the #action to null, effectively means #action becomes the same as your page URL, so for example if you're posting from http://www.mysite.com/node/add/forum/179, #action will become that. Works fine when editing the node too.

Dunx, thanks for posting your temp. solution.

It seems like this is still an issue with drupal core's AHAH handling. I will look into whether there is a way to put your workaround directly into the pollfield code until the Drupal core issue is fixed.

Agreed; it's a core issue, which hasn't been fixed for a long time and is causing pollfield to fail in this one scenario. Whilst it is only one scenario, it's not one that a site developer may come across, so may first hit site users. If there's a possibility of a pollfield solution, then that would be both fab and groovy.

Yeah, I agree with you dunx. I'll look into a workaround.

Great module... any progress on this?
