I’m working through Chapter 9 (enjoying the book!) and have come a little undone.
The methods on page 151 don’t appear to fire when I add or remove a user. I’ve gone back through and checked I did every step correctly, and all seems well. Is there something I’m likely to have done wrong?
I wondered if it was something to do with the action of the add and remove buttons. On page 137 we set the actions to add: and remove: respectively, but on page 152 you refer to them as insert: and remove:. Having said that, I changed the add button’s action to insert: and it made no difference.
The funny thing is: after fighting with this for a while I pushed on through adding edit undo and redo. That works!
I apologise if that was all far too vague. Let me know if you need any more info.
Thanks in advance for the help and for such a useful book!
