[MonoDevelop] Public Widgets using Stetic?

I'm a little unclear on how to interact with the code that stetic generates.
For testing purposes, I have a separate thread that's trying to update text
on 'label1' in my GUI, like so:

Gtk.Application.Invoke(delegate{ win.Title = updateVal; });

With 'win' being an instance of the 'MainWindow' class that Monodevelop
gives you for a gtk project. Inside 'MainWindow' I have:

public string Title {
		get { return label1.Text; }
		set { label1.Text = value; }

..but running gives me a 'NullReferenceException' on the set line in the
property.  It's acting as if it can't see the label1 object. so, two

1. What am I missing here to access the label?

2. Once I have this figured out, I'll be accessing a NodeView to update it.
What is the best way to update a NodeView?
