Objects don't passed in validator

[anton-makarov]

This condition in Validator.prototype.check don't converts objects without length fild into empty strings:
this.str = (str == null || (isNaN(str) && str.length == undefined)) ? '' : str;
Is it really necessarry?

I'm not sure what you're asking here. The condition isn't supposed to be an exhaustive way of converting non-strings into ''
