I went to WWDC, watched the binding stuff and am now trying to play with it
a bit. I'm following along with this tutorial:
file:///Developer/Documentation/Cocoa/Conceptual/ControllerLayer/Tasks/ccwit
hbindings.html
.. But am having trouble. I've read through and created the application
twice, get no compile errors, yet it doesn't work as expected (the amount in
other currency is never gets calculated).
I've set a breakpoint in amountInOtherCurrency and in debug mode notice that
it only breaks when the nib is opened, and never when the top two text
fields are edited. My hunch is that I need to do something to tell the
bottom text field he needs to ask the controller what the value is more
often. Does this have something to do with Key-Value Observing? Is it
working yet?
