I probed the autocomplete feature in IMP a longer time since now.
Before a few weeks something was corrected in the autocompleter code,  
but this is not what my problem solved, too.

The issue is, that the autocompleter will most of the time not show up  
until I wrote 4 letters, though I set ac_threshold to 1, even the  
maximum (200) can't be hit. Another time the autocompleter won't  
filter again, when typing the 3rd letter, typing the 4th will filter  
again.

This behaviour I get, when I use the hook as given in the examples:

     public function prefs_init($pref, $value, $username, $scope_ob)
     {
         switch ($pref) {
         case 'add_source':
             // Dynamically set the add_source preference.

             // Example: Useful hook when using a Turba source with shares
             // enabled (i.e. the example localsql configuration).
             return is_null($username)
                 ? $value
                 : $GLOBALS['registry']->call('contacts/getDefaultShare');


         case 'search_fields':
         case 'search_sources':
             // Dynamically set the search_fields/search_sources preferences.

             // Example #1: Use the list of sources defined in the contacts
             // application (e.g. Turba).

#Horde::debug($pref);
             if (!is_null($username) &&
                 $GLOBALS['registry']->hasMethod('contacts/sources')) {
                 $sources = $GLOBALS['registry']->call('contacts/sources');
                 if ($pref == 'search_fields') {
                     $out = array();
                     foreach (array_keys($sources) as $source) {
                         $out[$source] =  
array_keys($GLOBALS['registry']->call('contacts/fields',  
array($source)));
                     }
                 } else {
                     $out = array_keys($sources);
                 }
#               Horde::debug($out);
                 return json_encode($out);
             }

             return $value;
         }
     }


When I set this on my own in the preferences so that it will be saved  
in the pref-table, the autocompleter works correctly.
