Actually that does sound like a good idea Tito, will give it a try.
Thanks!
The core of the problem for me is that I don't have a complete handle
on inter-class communications. I know about sending messages and about
accessor methods...but in this case I am confused because I am creating
a window controller from another "parent" window controller and I'm not
sure how the second window controller should reference data from the
first window controller. The main window contains a tableView that I
want to let users double click on to open a second window with the data
from the selected row. Then they edit that data in the textfields and
then save it, which closes the second window and sends the edited data
back to the main window. Maybe I shouldn't have put that second window
in it's own nib, maybe I should have added the window to the main nib?
I've got 4 Cocoa books on the coffee table...time to do some reading!
Many thanks for all the help.

One solution could send a notification with an updated dictionary. The
window delegate (or a subclass of the window perhaps) would listen to
that notification, extract the values and refresh the UI. Finish with
a call to makeAndOrderFront.
Would that work for you?

I'd also like to hear answers to this...
If I am understanding your question correctly, what I have done in
these situations is to put the code in the window controller's
showWindow method. Usually I have a method such as refreshScreen
which clears controls or sets them to default values. I call this in
showWindow, and reset any variables too. Seems to work for me, but
maybe there is a more appropriate way...

Let's say you open a window and want to fill in some of the controls
with values (the window is in a separate nib). I create an instance
of
the new window's controller and load the nib. I use an init method to
load up the data in the fields. But if the user closes the window
then
reopens it it still has the old values...I'm assuming that's because
the window is not being released when it's closed, it's just being
hidden. What is the proper method to insure that I can load up the
values whether it's on the initial opening of the window or
subsequent
"unhiding"? Thanks in advance for any tips.
