I find out solution where I testing event.originalEvent.type if it is meneuselected or not and after fail I unset s_town_id. But any better solution is still wellcome.

<input id="s_town" type="text" name="s_town" />
<input type="text" id="s_town_id" name="s_town_id"  />

    
 $(function() {
  $("#s_town").autocomplete({
   source: function(request, response) {
    $.ajax({
     url: "/_system/_ajax/uiautocomplete.php",
     dataType: "json",
     data: {
      name: "s_town",
      term: request.term
     },
     success: function(data) {
      response($.map(data, function(item) {
       return {
        label: item.whisper_name+ " [" + item.zip_code + " / " + item.lup_state + "]",
        value: item.whisper_name,
        id: item.whisper_id, 
        zip_code: item.zip_code, 
        lup_state: item.lup_state, 
        stateid: item.stateid
       }
      }))
     }
    })
   },
   minLength: 2,
   select: function(event, ui) {
    $("#s_town_id").val(ui.item.id);
   },
   change: function(event, ui)
   {
    try
    {
        if(event.originalEvent.type != "menuselected")
        {
             // Unset ID
             $("#s_town_id").val("");
        }
    }
    catch(err){ 
        // unset ID 
        $("#s_town_id").val("");
    }
   }

  });


 });

if ui.item is not defined that means your json source is not well formed. You have to send a json source like this:

[{"label":"Jean","value":1},{"label":"carl","value":2}]

You can add more key to the array but at least you have to set "label" and "value". Check the json string. Also I reckon you to use the last version of autocomplete 1.8.1 at the moment
