Perhaps it is this bug here: https://www.macruby.org/trac/ticket/473
In my case with the current 0.5 beta2 no float or integer binding to nscontrol
works (I get all 1's) unless the float or integer is converted to an
NSDecimalNumber using a ValueTransformer.
This is what i use for each float binding as a work around:
class ToDecimalTransformer < NSValueTransformer
def self.transformedValueClass; NSDecimalNumber.class; end
def self.allowsReverseTransformation; true; end
def transformedValue(value)
NSDecimalNumber.decimalNumberWithString(value.to_s)
end
def reverseTransformedValue(value)
new_val = value.to_f
end
end
HTH,
John
