Here is the error:

Notice: Undefined index: #value in forum_form_alter() (line 589 of /home/quickstart/websites/

It seems when I create a view using Views UI that has an exposed filter and is letting me view taxonomy vocabularies (with the forum vocabulary) I get the error.

The code in forum.module has:

function forum_form_alter(&$form, $form_state, $form_id) {
  if (isset($form['vid']) && ($form['vid']['#value'] == $vid)) {

For my view's form the vid is defined but has no #value sub key. I'm guessing the forum.module didn't take into account the possibility of other forum taxonomy forms passing through hook_form_alter.

To get to that error using Quickstart 0.9 VM:

Drush a D7 clean install with ctools and views. Enable Views UI. Enable forums.

Add two vocabularies; "Assignee" and "Status", each with several terms.
Add a forum container and move the default forum into it.

Import the view. Put the block on a page and whenever you go to that page you get the error.

This code seems to fix it but could easily whack somebody else - this would need somebody smart then me to look it over:

Change that if to be this:

  if (isset($form['vid']) && isset($form['vid']['#value']) && ($form['vid']['#value'] == $vid)) {

Actually, checking for isset($form['vid']['#value']) is enough here.

Looks good

I nearly asked for tests but the patch is trivial and creating the test would be quite a lot to add. Committed to 8.x, moving back to 7.x for webchick.
