strange: can't access public var in model in Cairngorm

[madhooper]

I can access the public const but not the pubic var in my model. Can someone tell me what's the problem?  Thanks in advance.

package model

{

import com.adobe.cairngorm.model.IModelLocator;

[Bindable]

public class ModelLocator implements IModelLocator {

// Single Instance of Our ModelLocator

private static var instance:ModelLocator;

public function ModelLocator(enforcer:SingletonEnforcer) {

if (enforcer == null) {

throw new Error( "Hey, You Can Only Have One ModelLocator" );

}

}

// Returns the Single Instance

public static function getInstance() : ModelLocator {

if (instance == null) {

instance = new ModelLocator( new SingletonEnforcer );

}

return instance;

}

//MY VARIABLES HERE 

public var  workflowState:uint = 0;

public var  gotit:String = "Dameon";

//MY CONSTANTS

public static const SEARCH_SCREEN = 0;

public static const DIAGRAM_SCREEN =1;

}

}

// Utility Class to Deny Access to Constructor

class SingletonEnforcer {}
