[development] Question on AHAH

[Hadubard]

This should be working. But you need indeed to tell ahah about the new form. Did you follow the descriptions on http://drupal.org/node/331941? Have a look at the quicktabs_ahah() function and the usage of $javascript['setting']. If I remember correctly than this is one of the keys to introduce your dynamic elements and register their behaviors.

best regards,
