On page 200, “Control-drag” from the Add Employee button to the File’s Owner". Presumably this negates the “Control-drag from the Add Employee button to the Array Controller” on page 165. It would be nice for the reader to tie this all together and then state that is the reason that the addEmployee method on page 201 is so long. The addEmployee method must reimplement what the array controller was doing in the Chapter 9 implementation. Or maybe it isn’t and I don’t understand. Either way, some discussion of the connection between page 200 and 165 would be helpful.
The authors gave up on teaching at this point. See the other post about the addEmployee() method for some explanations.
