Yes, I set up a master/detail view and IB automatically set up the add button...
Enabled:(threeAttributesEntityArrayController.selection) which is described
as a multiple-value binding that determines if the NSButton is enabled in the
user interface.
You wrote: "...master-detail view going on, where you can choose which entity
you want to work with on the main window, and then play with its properties on
a sheet..." How does this work?
Thanks
Rick Tschudin
PS What I am tryin to do is get an attribute of an entity to appear in 2
separate tableview displays
1. in a document window
2. in a Panel of the document window.
I want to make changes in the Panel and have the changes appear in the document
window when the panel is closed?
