Re: New RelayResponder in AS 2.0 Components

Hi,
the following is how I use it today on client side. I don't do anything
specific on my app srv side.
hope this'll help,
seb.

* CreateNeClip.as

  m_controller.createNe(neId, type, release, userLabel, acd, tlocation,
  userName, password, hostname, port,
  pa, sa, this);
 }

* TopoController.as

 public function createNe(neId:Number, type:String, release:String,
userLabel:String, acd:String, tlocation:String,
   userName:String, password:String, hostname:String, port:Number,
  pa:String, sa:String, clientContext:Object):Void
 {
  Util.debug("TopoController::createNe with userLabel " + userLabel + "
---");
  // NOTE: WE SHOULD CHECK THE STATE OF THE OBJECT HERE FIRST
  m_delegate.createNE(new
TopoRemotingContext(this,"createNe",arguments,"createNeCbk","errorCbk",clientContext),

       Number(neId), type, release, userLabel, acd, tlocation, userName,
password, hostname, port, pa, sa);
 }

 public function createNeCbk(res:RecordSet, context:Object):Void
 {
  if ((context != null) && (context != undefined))
  {
   var ctx:TopoRemotingContext = TopoRemotingContext(context);
   var msg:String = "TopoController::" + ctx.callingFunc + " SUCCESS for
";
   msg += arg2string(ctx.callingArgs);
   Util.debug(msg);
  }

  for (var i = 0; i < res.length; i++)
  {
   var row:Object = res.getItemAt (i);
   m_nesModel.addItem(row);
  }
  // note that reacting on events would be more generic, but event does
not contain all dbValue info for now (only neId)
  /*
  var it:Iterator = res.getIterator();
  while (it.hasNext())
  {
   m_nesModel.addItem(it.next());
  }
  */
 }

* TopoDelegate

 public function createNE (tRspd:TopoRemotingContext, neId:Number,
type:String, release:String, userLabel:String, acd:String,
tlocation:String, userName:String, password:String, hostname:String,
port:Number,
 pa:String, sa:String):Void
 {
  s_log.logDebug ("TopoDelegate::createNE " + neId);
  Object.registerClass ("com.alcatel.gem.ems.ne.interfaces.NEDBValue",
NEDBValue);
  Object.registerClass ("com.alcatel.gem.ems.tl1.types.TelnetNEAddress",
TelnetNEAddress);
  Object.registerClass ("com.alcatel.gem.ems.tl1.types.NEAddress",
NEAddress);
  var o:Object = new NEDBValue ();
  o.setNeId (Number (neId));
  // problem here ? o.type is gonna be used per OpenAMF
  //o.type = "com.alcatel.gem.ems.ne.interfaces.NEDBValue";
  o.setType (type);
  o.setRelease (release);
                o.setLocation (tlocation);
  o.setUserLabel (userLabel);
  o.setAccessControlDomain (acd);
  var ta:TelnetNEAddress = new TelnetNEAddress ();
  ta.setPort (3082);
  o.setPrimaryAddress (null);
  o.setSecondaryAddress (null);
  var pc:PendingCall = m_service.createNEs ([o]);
  pc.responder = tRspd;
 }
