Thanks, but the accessibility-dev is by itself arcane, to say nothing of
Accessibility engineers.. :)
I've been trying to get useful info there for many issues I had in the past, to
no avail. I was hoping to have at least the non-accessibility issues helped
here.

I'm going to re-read Chapter 31 and 32 of Hillegass' book, which more or less
cover this subject (view swapping and core data relations). Briefly what he
does is is adding a MOC property to each view controller, so its views can use
that. I'll post back later.

It works now! The problem was, that I was creating the window manager with
"init:", instead of the initializers from the docs.
Thank you all for the replies, they were very helpful!

Subclassing NSDocumentController is extremely rare, and in almost every case,
unnecessary. If you're doing this as a matter of course because you thin

Hi,
We are using a third party library that performs tasks
asynchronously. This is ok most of the time, but on some occasions
I'd like to be able to wait (not on the main thread) until an
operation completes,
The flow basically goes like this:

Should have added, this is for iOS and doesn't have to run on Mac.

Hi Ken,
Thanks for that I will try it out tomorrow, as an aside, is this ok/
recommended?
-(void) someMethod:(NSString*) theParameter
{
if ([NSThread isMainThread)
{
[self performSelectorInBackground:@selector(someMethod:)
withObject:self];
return;
}
// Do work
}

No the caller is always expecting it to be ASync. It's just that I

I have a menu item connected to an action in First Responder;
The action exists in an NSView subclass.
The subclass implements acceptsFirstResonder and return YES.
The subclass implements validateMenuItem and return YES;
When the menu displays the menu item is disabled (set to enabled in IB).

I have had this happen when I have forgotten to declare my action method in the

Yes, the subclass implements the action.

The action is declared in the subclass header.

Could you please paste the a copy of the method in a message? It is far easier
to help you debug code which we can see than a description of something we
cannot see.

Hello,
the questions are:
1. What equations are used to transform CALayers in 3D space and project their
2d point {x, y, z} to the 2D surface {x, y} ?
All equations that I've found to project 3D points onto 2D space aren't the
same with what CALayers use.
My solve is to get one coordinate {x, y
. in a pre-emptive OS there should be no freezing;
given the new concurrency model
that includes the use of the graphics processor GPU
to do the system's non-graphics processing,
my current guess is that the freezes happen when
something goes wrong in the GPU,
and the CPU is just waiting forever .
