[support] Changing checkboxes options during hook_node_validate

[Jeff Greenberg]

Ok, did that , and the #validate function is firing. I might get this
wrong, because my confusion level is high, but here is what I think I
observe in xdebug.

When I was setting a form error during validation, when it eventual made
its way to drupal_process_form it wasn't doing a rebuild because of that.
So I tried not setting a form error, since I'm setting
$form_state[rebuild]=true anyway. Now drupal_process_form does a rebuild,
but what happens is that just prior to the rebuild, the #options are what I
just set them to with
   $form[my_field][LANGUAGE_NONE][0][#options] = my_options_array;
in validation, but right after the rebuild, the original value is back. Do
I need to set #options in more than one section of $form or somewhere in
$form_state?
