Error in canvas.draw() using smartgwtee-4.0p Error

When running code that ran with prior versions of smartgwt ee I am seeing and error when the statement:

canvas.draw() is run.

The error returned gives a grey screen(see attached) with the error:

@com.smartgwt.client.widgets.BaseWidget::draw()([]): Object doesn't support property or method '$105p'

Here is the full stack trace:

08:13:12.818 [ERROR] [builtinds] Unable to load module entry point class com.smartgwt.sample.client.BuiltInDS (see associated exception for details)

I'm kind of dead-in-the-water at this time. The Javadocs for Canvas show the draw() method inherited from BaseWidget.

Any help would be greatly appreciated.
