warning: Invalid argument supplied for foreach() in /tmp/drupal/includes/form.inc on line 232. where line 232 is foreach ($form['#parents'] as $parent) { so I add if (!is_array($form['#parents'])) var_dump($form['#parents']);. I get an 'L'. OK, this have not helped much -- $form is a string where the 0th offset is an L, so let's dump$form>! string(17) "Leave shadow copy" Oh! There you are. A # was missing in the title. So easy.

Sometimes it's element_child. It's still easy -- the if (!is_array( is always the same and you have $form or $element in it, depending on the situation.
