[MacRuby-devel] Cocoa Bindings not writing?

[Robert Payne]

I actually solved this. It turns out I did not set the flag "Continuously Update Value" on the binding so it would only update if you actually pressed enter.

The name/setName methods I only defined to test if they were getting called and attr_accessor actually generates these for you.
