I'm working to extend the Home Widget to add functionality for multiple views. The reference docs say that "Any properties can be set, retrieved or listened to." But when I try to set iconClass or label properties, either through super() with the properties object or by setting them via my class, I get an error stating that it cannot assign because the property is constant or read-only.

What gives? Is the doc wrong?
