Cannot access friends information.

[Joachim Petersen]

Hello I am using this code:

           function onFriendsListLoaded(response){
            //alert("divTarget="+divTarget+"\ndata="+data);
                for (var friendIndex=0; friendIndex<data.length; friendIndex++){
                    //divContainer.innerHTML="<hr><img src='http://graph.facebook.com/"+data[friendIndex].id+"/picture'></img>"+
                    //"<br>"+data[friendIndex].name;
                    //divTarget.appendChild(divContainer);
                    trace(data[friendIndex].name)
                }
            }
           
            function showFriendsList(){
                FacebookMobile.api('/me/friends', onFriendsListLoaded);
            }

I am getting this error:
onFriendsListLoaded(). Expected 1, got 2.

Anyone know why that code is not working?

every api callback must accept two paramaters response and fault

so you'll function definition should be : 

 function onFriendsListLoaded(response, fault){

.....

}

response hold the returned data if the request is seccessfull and fault will be null

if the request not sucessfull the fault will contain the error message etc... and responce will be null

function onFriendsListLoaded(success, fail){
                if (success){

                    for (var friendIndex=0; friendIndex<data.length; friendIndex++){
                        //divContainer.innerHTML="<hr><img src='http://graph.facebook.com/"+data[friendIndex].id+"/picture'></img>"+
                        //"<br>"+data[friendIndex].name;
                        //divTarget.appendChild(divContainer);
                        trace(data[friendIndex].name)
                    }
                }
            }

now it return null error:

Error:

[Khaled Garbaya]

in you your trace(data[friendIndex].name) it should be trace(success[friendIndex].name)

It is this line that triggers the error:

for (var friendIndex=0; friendIndex<data.length; friendIndex++){

[Khaled Garbaya]
