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
Vince Ackerman
