alice-teacher Chapter 5 Zeus Exercise (in Dann, Cooper, Pausch) not working

[Rigole, Neil]

Hi All,

I have a group of student using Alice v2.2 (12/01/11) along with the
Learning To Program with Alice textbook. For Chapter 5, the "Zeus"
exercise worked through in the chapter, we're getting a "target value
must not be null" when running the code. We're using when the mouse is
clicked on anything event, and it seems that our "target" object
parameter is not being recognized in our "prepareToShoot" method. Any
clues or advice? This worked for me in the past with the older version
of Alice and the same code, but not now.
