[MacRuby-devel] programatic binding (undefined bind method on NSTextField)

[Sven A. Schmidt]

Have you got the right signature? Looking at 

http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ApplicationKit/Protocols/NSKeyValueBindingCreation_Protocol/Reference/Reference.html

I see only

  bind:toObject:withKeyPath:options:

and on Lion with macruby_nightly-2011-09-23 I get:

irb(main):014:0> NSObject.alloc.init.respond_to?('bind:toObject:withKeyPath:options:')
=> true
irb(main):015:0> NSTextField.alloc.initWithFrame([1,2,3,4]).respond_to?('bind:toObject:withKeyPath:options:')
=> true

Cheers,
Sven
