[RESOLVED] RangeError: Error #2006: The supplied index is out of bounds. HELP!!!

Hi,
I made shared object application with drawing lines, arrow and circles. Almost everything works fine until I restart application.
Not every time but very often I get this error:
RangeError: Error #2006: The supplied index is out of bounds.
This is code which loading share objects:

function addNewChild(data, name) {
var child = null;
switch(data.toolType) {
case "brush":
child = new ScrappyBrush();
break;
case "arrow":
child = new ScrappyLine();
break;
case "text":
child = new ScrappyTxt();
break;
case "textBox":
child = new ScrappyTxtBox();
break;
case "circle":
child = new ScrappyCircle();
break;
case "bitmap":
child = new ScrappyBMP();
break;
}
if (child) {
child.name = name;
dragTarget.addChild(child);
child.updateSharedObject(this.so);
}
}

I was trying to replace dragTarget.addChild(child); to dragTarget.addChildAt(child,0); but that did not solved my problem.

Can anyone explain me what is wrong?

I don't see anything in that code that would throw an index error - can you post the full trace when the swf fails? That should show you exactly what function is breaking. (I suspect it's in one of those constructors)

First thx for replay :)
The problem is that error is only thing what I get. But I was wrong with one thing - replaceing
dragTarget.addChild(child); to
dragTarget.addChildAt(child,0);
solved problem with loading shared objects. Unfortunately the same error message I get during connection with media server (but not every time) . Usually when I draw more objects.
Code to connect and sync with media server:

function mainInit() {
// create a connection to the media server
nc.addEventListener(NetStatusEvent.NET_STATUS,netS tatusHandler);
nc.connect("rtmp://localhost/whiteboard");
this.so = SharedObject.getRemote(args.gidReq+"-"+args.cidReq, nc.uri, true);
this.so.addEventListener(SyncEvent.SYNC,syncEventH andler);
this.so.fps = 0;
this.so.connect(nc);
}

public function netStatusHandler(event:NetStatusEvent):void {
trace(event.info.code);
}

public function syncEventHandler (event:SyncEvent) {
var list = event.changeList;
for (var i = 0; i<list.length; i++) {
if (list[i].name == null) continue;
trace(list[i].name);
if (list[i].code == "delete") {
// Shape has been deleted, remove it.
this.dragTarget.removeChild(this.dragTarget.getChi ldByName(list[i].name));
} else {
var child = this.dragTarget.getChildByName(list[i].name);
if (child)
child.updateSharedObject(this.so);
else
this.addNewChild(this.so.data[list[i].name], list[i].name);
}
}
}

I thought this error concern only addChild function, but I was wrong :(
I'm sure that constructors are ok.
Please give me some idea what can be wrong :(

Finally I solved that :)
The problem was in function mainInit(), I replace part of the code from this function to the function netStatusHandler
Code:

function mainInit() {
// create a connection to the media server
if(nc == null){
nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS,netS tatusHandler);
nc.connect("rtmp://localhost/whiteboard");
}
}

public function netStatusHandler(event:NetStatusEvent):void {
if(event.info.code == "NetConnection.Connect.Success") {
this.so = SharedObject.getRemote(args.gidReq+"-"+args.cidReq, nc.uri, true);
this.so.addEventListener(SyncEvent.SYNC,syncEventH andler);
this.so.connect(nc);
trace(event.info.code);
}
}
