[development] Multiple similar Forms on same page

Hi All I'd like to show the same form multiple times on one page. I tried to do this by calling drupal_get_form in a loop. Unfortunately this doesn't work since drupal makes them 100% identical (same form id and form-token) which means up on submition drupal cannot tell which form has sent the answer. Note that the forms are not 100% identical, they differ by things like item id and selection options. This is handled in the form building function. What's the right way of implementing this? Best Regards Ernst
