Absolutely agree. As I said originally, relying on the order of the properties in the object is almost always a bad idea. @somonek, an object with an array of keys is probably your best solution. Wrap it up in an object with an API that all of the code updating it can use, so you don't have consistency issues. You could even give it an iterator. :-) -- T.J.
