Devel User Switch does not work as expected

Patch worked for me. Thanks.

Confirmed patch in #1 works nicely.

Just another note to say I've just re-patched an admin module with dereine's patch in #1 and it's working fine. I've marked this as reviewed but maybe I'm overstepping the mark so forgive me if this needs more testing.

This patch still works great as of 10/11/12 with devel 6.x-1.27.

I had this issue with Drupal 7.31 and Admin 7.x-2.0-beta3+8-dev. You can also apply this change and it will work perfectly:

-    $panes['switch_user']['user']['#submit'] = array('devel_switch_user_form_submit');
+    $panes['switch_user']['user']['submit']['#submit'] = array('devel_switch_user_form_submit');
   }
   if (user_access('execute php code')) {
     $panes['execute'] = devel_execute_form() + array('#title' => t('Execute PHP'));

What are the steps to reproduce this? I have seen the user switcher fail silently before, but it may have been with an older version of Devel or Admin. I can't reproduce now on Drupal 6 or 7.

I am not convinced that this patch is necessary because I think since there is only one submit button it shouldn't matter whether the submit callback is added to the form or the submit button. However, a reroll is attached because the other one didn't apply.

I have never seen the switch user form work in the admin bar, and while I made the change manually versus trying the patch, I can confirm the change solves the problem.

I could always switch to the users that were listed in the block, since those were direct links to devel/switch/[username], but the form where you type in a user has always failed for me until I apply this change.

A change in Devel makes this patch no longer work.
#2448063: Add #actions container to submit buttons.
I opened #3020764: Devel blocks do not submit to fix more than just the user switch block.
