Maybe don't do model = new ModelLocator() in the getInstance() function
since you'll assign ModelLocator.model in the constructor?

Subject: [cairngorm-devel] FlexPhoneBook ModelLocator problem

I'm trying to implement a ModelLocator similar to the one use in the
FlexPhoneBook example. However, whenever I try to compile the app, I
get
a java.lang.StackOverflowError in FlexXmlServlet (with no stack
trace). If I remove the getInstance function, it compiles fine. Can
someone explain what my problem is? Thanks for your assistance.

Code below:

import control.*;
import vo.*;
import model.*;
import de.richinternet.utils.Dumper;

class model.ModelLocator
{

private static var model : ModelLocator;
public static var statusMessage : String = "";


public static var users : Array;
public static var selectedUser : UserVO;
public static var trees : Array;
public static var selectedTree : TreeVO;
private var _tasks : Array;

public static var selectedTask : TaskVO;

public static function getInstance() : ModelLocator {
Dumper.dump("modellocator getInstance");
if( model == undefined ) {

model = new ModelLocator();
model.initialize();
}
return model;
}

public function ModelLocator() {
if( ModelLocator.model != undefined ) throw new Error( "Only one
Model instance should be instantiated" );
ModelLocator.model = this;
mx.events.EventDispatcher.initialize( this );
}

public function initialize() : Void {
selectedUser=new UserVO();
selectedTask=new TaskVO();
selectedTree=new TreeVO();

}


public function get tasks() : Array {
if (_tasks == undefined) {
EventBroadcaster.getInstance().broadcastEvent
("getTaskList");

}


return _tasks;
}
public function set tasks(data: Array): Void {
_tasks = data;
}


}
