[support] Changing checkboxes options during hook_node_validate

[Jeff Greenberg]

Tried this. So my function signature is:
function si_core_node_validate($node, &$form, &$form_state) {

and the last thing I do is:

            $form['refs'][LANGUAGE_NONE][0]['#options'] = $options;
            $form_state['rebuild'] = TRUE;
            form_set_error('refs', 'Select the potential entity links to be
processed.');

yet the form displays the original field option.
