All,
I have a problem with an application. I am using Core Data for my
data store, and the interface uses bindings to NSArrayController to
present, add and modify the information.
In the main Window (window Outlet of AppDelegate) undo works fine.
Any additions, removals or changes to values can be undone by
pressing Apple-Z.
In all of the panels (I've only got the one window, everything else
is a panel), undo does not work at all.
I've not implemented any undo features, just using what I got for
free from Core Data. Do I have to implement any for these subsequent
windows / panels?
If so, how do I go about integrating this with the NSArrayController?
Do I have to subclass this for each NSArrayController I use?
Also, I'm not sure if this is related or not, but my window, all of
my panels and my MainMenu all have a little yellow exclamation mark
in the lower left of the icon. When I mouse over the icon, I get the
following message: "One of the children has a bad / missing
connection". Google doesn't tell me much about this error so I'm not
sure if it's related or not.
Thanks in advance,
