#4 about NumberScaleValidator

[Anonymous]

See the ColorUtils class and the method toHexValueWithRGB is defined as follows:
ColorUtils.toHexValueWithRGB=function(redValue,greenValue,blueValue){
var flag1=NumberScaleValidator.validateBetween(redValue,0,255);
var flag2=NumberScaleValidator.validateBetween(greenValue,0,255);
var flag3=NumberScaleValidator.validateBetween(blueValue,0,255);
...
};
But NumberScaleValidator can not be found in jsjava-2.0.js.So I get a js error.
