Hi List, I have a NSPopUpButton to which I bound the NSString "selectedPort" using an NSObjectContoller and the "selectedValue" binding (Controller Key: "selection"). Everything is working fine (selectedPort gets updated when the selection changes) as long the changes are made using the GUI. But if NSPopUpButton's selectItemAtIndex is called, then selectedPort still has it's old value. As I am fairly new to bindings I am wondering if those do not work if the selection is changed programatically?
right. they don't. Changing the control programmatically does not update value.
    instead, set the value directly, and the control will update.

Thanks for the answer Scott, this clears things up.
