[support] Changing checkboxes options during hook_node_validate

[Jeff Greenberg]

Ok, I've tried that. The last thing I do in hook_node_validate is
$form_state['rebuild'] = true; What I notice is that
hook_form_node_form_alter does not fire between then and the form being
redisplayed, so my pulling the options from $form_state['storage'] never
happens.
