I found that the materialized object did not have a reference to the Bloc
space. With the line of code introduced below the error disappeared.
| container materializedObject objectToSerlialize |
container := BlMorph new withRectangleViewDo: [ :v | v extent: 200@200. v
color: Color lightCyan ].

The code below works but it turns out the error "Message Not Understood:
receiver of" noticeMouseOver "is nil" when the mouse passes over the morph.

container := BlMorph new withRectangleViewDo: [ :v | v extent: 200@200. v
