Hi Brian, This is currently a well-known limitation of MacRuby, we will address it in the future. In the meantime, you might have to work-around it by doing this extra check. Laurent On Feb 12, 2009, at 7:03 AM, Brian Marick wrote:
Is this a bug? I don't see anything quite like it in Trac.
I have a binding to a button's state property. Here's the binding:
@comboBox.bind 'enabled', toObject: @button, withKeyPath: 'state', options: { NSValueTransformerBindingOption => OffStateMeansTrueTransformer.alloc.init }
At the point the binding is made, the state of the button is a fixnum 0.
The value transformer is immediately called to set the starting value. Here's the transformedValue code:
def transformedValue(state) puts "state -> bool transforming #{state.inspect}" # prints #<NSCFNumber:0x1022180> # state.intValue is 0
Because of this, I have to cast the state before making comparisons:
case state.intValue when NSOffState then true when NSOnState then false else raise "The value to transform should be either NSOffState or NSOnState." end
If this is a bug, I'll write a testcase.
