I have a NIB with a NSView that I use to populate a Contextual View

from init, from awakeFromNib, and from - (BOOL)control:(NSControl

All of these work in 10.5 (+), but only that last works in 10.4.
Unfortunately the side effect of the last is that if the user clicks
on a different edit field and starts to type, the focus is on the
firstResponder instead of the field the user just clicked on.
I am sure I can continue to ________ with this, but it seems like
there must be a better way. It seems unlikely that 10.4 is this
messed up and it will not correctly set the firstResponder.
Any hints as to what I am missing?
It's very unclear what you're trying to do.
My interpretation is that you have a custom view, and you want to make
it first responder? You don't "set" first responder in most cases.
Instead, implement -acceptsFirstResponder and -canBecomeKeyView to
return YES, and hook up the window's initialFirstResponder outlet to
your view. If there are other candidates for first responder in your
window, the user should be allowed to change it, so you may also want
to include your view in the key loop (nextKeyView, previousKeyView),
or set this to be recalculated automatically, and make it draw a focus
ring when it is first responder.
To force a specific view to become first responder, you need to use
the window's -makeFirstResponder: method, not by calling -
becomeFirstResponder on the view itself - but doing this is usually
unnecessary as you can set the initialFirstResponder in IB.
If this is irrelevant info, then you'll need to be clearer about what
you're trying to achieve, and your current code.
