Ben,



Your variables inside your TestModel souldnt be static except
for your modelLocator holder. 

When you do myModelLocator.getInstance() this function returns
an unique instance  of your modelLocator.

Whoops. Updated code, which now produces an
error concerning Access
of a possibly undefined property 'name' through a reference with
static type TestModel. My label tag now looks like this:

mx:Label x=130 y=136 text={TestModel.getInstance().name}
id=testLabel/

And the TestModel class is updated to look like the sample in the
documentation:

package
{
import com.adobe.cairngorm.model.ModelLocator;

[Bindable]
public class TestModel implements ModelLocator
{
public static var name:String;
private static var modelLocator : TestModel;

public static function getInstance() : TestModel 
{
if ( modelLocator == null )
modelLocator = new TestModel();

return modelLocator;
}

public static function initialize():void
{
name = Some text;
}
}
}

You don't use static's in Cairngorm 2's ModelLocator.  Use instance level 
vars.  So:

public static var name:String;

should be:

public var name:String;
