Scott, mmalc and others:
I've read all the Apple Docs under Manual / Automatic KeyValue
notifications and still can't seem to get two tableviews to update
correctly. I've basically modified Scott's email example to fit my
project, but want programmatically use the addEmail method rather than
the binding "add:", so I can set the row number value to the new
email. The tableview bindings all work fine when hooked up as per
Scotts example, but when I disconnect the add: binding (and use the
addEmail method in the controller object) I still don't see the email
tableview update itself. It will finally update when I select any
other mailbox or blank row in the mailbox tableview then select the
new mailbox row again.
I've added the following which doesn't seem to work:
[self willChangeValueForKey:@"emails"];
[emails addObject: newEmail];
[self didChangeValueForKey:@"emails"]
Looking at Scott's example, the key @"emails" is the NSMutableArray
that contains the pointer to the mailbox array of the currently
selected row in the mailbox tableview. I'm confused how this pointer
is a "key" and how this will send a notification that I've modified
the mailbox array? Do I have to turn off Automatic KVO notification
prior to using this?
TIA
