help belongs_to_auto_completer model_auto_completer

hi,

im trying to integrate model_auto_completer. the dropdown is working nicely, my userdefined function: auto_complete_belongs_to_for_X_Y_Z works as well, but then im stuck. via model_auto_completer_result i can see the id, either attached to the model(eg account_ID) or via my own partial: <ul>      <% for author in @authors %>      <li id="<%= author.id %>"><%=h author.title %></li>      <% end %> </ul>

but what i wann do is: as soon the user selected one entry out of the dropdown, i need to populate the rest of the form with data related to the unique ID of that record. so> how to i access the ID???

thx tom
