flex access modifier and usage within library

[Serkan Taş]

Hi,

I extracted the sources of fds.swc and library class 
*ConcreteDataService.as***uses method *mx_internal function 
setResult(newResult:Object):void* .

public function applyChangedItems(changedItems:ChangedItems) : AsyncToken
      {
         var applyToken:AsyncTokenChain = null;
         var refreshAllLocalFills:Function = function():void
         {
            var currDataList:DataList = null;
            for each(currDataList in _dataLists.toArray())
            {
applyToken.addPendingInvocation(refreshLocalFill,currDataList);
            }
         };
         applyToken = new AsyncTokenChain();
applyToken.setResult(changedItems);

According to the definition of the method in***mx.rpc.AsyncToken* the 
function is private and i can not compile the fds.

In flex, the fsd.swc is included in my project and everything is working 
fine. How can this happen any idea ?

Thanks,
Serkan
