I believe that when NSViewAnimation finishes and a view's frame is 0
width or height its hidden flag gets set.
From the docs (specifically in the description for the
NSViewAnimationEndFrameKey):
"If the target is a view and the end frame is empty, the view is
hidden at the end."
You may want to try using setHidden:NO on the Notes view before the
start of the animation. Personally, I feel NSViewAnimation should do
this for you but you have to play with the cards you're dealt.

Yeah, I thought of that, but I don't think this is the problem.
The view itself (right now) is a custom view that draws its own
background. It has 2 "springs" set in IB -- one to resize
vertically and another to have a flexible outer right side (the
side with the "content" view). Everything else is static. And I've
tried removing the settings with no beneficial effect.

I'm assuming the notes section uses some auto-sizing flags? When
the frame gets set to 0 width, the subviews are auto-sized to 0
width as well. When you attempt to size them up, they remain at 0
width because x * 0 = 0.

Hello!
I have two views, side by side. One is the main "content" of the
window, the other is a "notes" bar.
I am using NSViewAnimation to open and close the Notes section.
To close the Notes, I set the Notes view frame to 0. When I open
it, I set it to 150.
If I use setFrame: to open and close the Notes everything works
fine. When I use NSViewAnimation, however, things get screwy. I
can close the Notes just fine, but when I open them, the view
doesn't appear. I've NSLogged the before/after frame width and
NSViewAnimation seems to be doing its job, but the view simply
doesn't show.
After messing around with it for a while, I noticed that if I set
the "closed" width to 1 instead of 0, everything works fine!
Is this a bug or a known issue? Is there a workaround? Right now
I'm setting the closed width to .00001 -- it works, but it seems
like a hack. Any ideas?
Thanks!
August
