_WidgetBase tutorial error about event handling

[bill]

From the mailing list, http://dojotoolkit.org/documentation/tutorials/1.7/understanding_widgetbase/ has some errors. It says:

btn.on(foo, "bar", function(){
    //  note that "bar" is executed in the scope of btn!
    this.set("something", somethingFromFoo);
});

but should be

btn.on("event", function(){
 ...
});

I'm not sure what you were trying to get at with "foo" or "bar" in the original example.

Also, subscribe() is mentioned in your tutorial although there's no example. It shouldn't be mentioned at all since it's a protected method.

I didn't write that; it must have been an alteration with the updates from 1.6 to 1.7 tutorials, and I have no idea who made those updates. Reassigning to brianarn for direction.

I will fix. Note that the code was wrong initially, misunderstanding what connect() and subscribe() were for, and got further confused when the connect() description was converted to on().

Updated tutorial to just explain connect() and subscribe(). For the 1.8 tutorial, can explain both on(), and this.own().
