title: Why would a Drupal form not be cached in cache_form?
body: <p>My form, lets call it <code>organize_issue</code>, is a form in a custom module being called from the menu using the page callback <code>drupal_get_form</code> function. The form works perfectly well.</p>
  
  <p>I'm trying to implement some AHAH type functionality now, and need to get the page from cache using <code>form_get_cache($form_build_id, $form_state)</code> but, oddly enough, my form isn't being cached. Ever. Other forms on the site are, just not this one. As I said the form works fine, and submits and validates and whatnot... it just never caches. Is their something simple I'm missing?</p>
