Monitoring it behind

Astatine archetypal I idea this was a coercion bug wherever null was getting coerced to "null" and a trial of "null" == null was passing. It’s not. I was adjacent, however truthful precise, precise incorrect. Bad astir that!

I’ve since finished tons of fiddling connected wonderfl.nett and tracing done the codification successful mx.rpc.xml.*. Astatine formation 1795 of XMLEncoder (successful the three.5 origin), successful setValue, each of the XMLEncoding boils behind to

currentChild.appendChild(xmlSpecialCharsFilter(Entity(worth))); 

which is basically the aforesaid arsenic:

currentChild.appendChild("null"); 

This codification, in accordance to my first fiddle, returns an bare XML component. However wherefore?

Origin

In accordance to commenter Justin Mclean connected bug study FLEX-33664, the pursuing is the wrongdoer (seat past 2 exams successful my fiddle which confirm this):

var thisIsNotNull:XML = <base>null</base>; if(thisIsNotNull == null){ // ever branches present, arsenic (thisIsNotNull == null) unusually returns actual // contempt the information that thisIsNotNull is a legitimate case of kind XML } 

Once currentChild.appendChild is handed the drawstring "null", it archetypal converts it to a base XML component with matter null, and past checks that component in opposition to the null literal. This is a anemic equality trial, truthful both the XML containing null is coerced to the null kind, oregon the null kind is coerced to a base xml component containing the drawstring “null”, and the trial passes wherever it arguably ought to neglect. 1 hole mightiness beryllium to ever usage strict equality exams once checking XML (oregon thing, truly) for “nullness.”

Resolution

The lone tenable workaround I tin deliberation of, abbreviated of fixing this bug successful all rattling interpretation of ActionScript, is to trial fields for “null” and **flight them arsenic CDATA values.**CDATA values are the about due manner to mutate an full matter worth that would other origin encoding/decoding issues. Hex encoding, for case, is meant for idiosyncratic characters. CDATA values are most popular once you’re escaping the full matter of an component. The greatest ground for this is that it maintains quality readability.
