[support] Changing checkboxes options during hook_node_validate

[Metzler, David]

Also make sure your hook_form_alter has & signs in front of the $form parameter (as well as $form_state) to indicate pass by reference.  It’s easy to overlook that if your field isn’t changing when you think you should. If you forget to do this hook_form_alter won’t actually alter anything, but it won’t give you any errors either.

mymodule_hook_form_FORMID_alter(&$form, &$form_state);

One thing that is either part of the issue, or a separate issue that impacts this, is that the checkboxes field is added via hook_form_alter. I notice that although the field appears in $form_state[values] it does not appear in $form_state[field], so I'm wondering where $form_state gets the information for the field when rebuilding the form.

I have a node form that contains a checkboxes field with options NULL at the time the form is displayed.

During node_validate, if certain criteria is met, an array of options (checkboxes) is created, and the form needs to be redisplayed with the checkboxes as part of it.

I've tried setting #options = the new array in the $form, in $form_state[original_form], etc all to no avail. The field doesn't change.

I also set one checkbox in the field at the start, so that I could find it in the $form and $form_state structures, changed where I found it to the new options array, and again, no change. I am setting $form_state[rebuild] to true, and even tried explicitly calling for the form to be rebuilt.
