I typed the following in a workspace and created a rectangle:
FirstBox := RectangleMorph new openInWorld.
I then changed its color:
FirstBox color: Color green.
I next created a system category with a RectangleMorph subclass:
RectangleMorph subclass: #TestBox
I then used a workspace to create a new rectangle:
SecondBox := TestBox new openInWorld.
But I could not change its color like I could with the first rectangle:
SecondBox color: Color green.
How can I change the second rectangle’s color by sending it a message from a workspace?
