We've implemented a C-based Javascript class with a callback for the getPropertyNames function. Normally, this function is called anytime one of our objects is iterated via a for/in loop, i.e: "for (property in object) {..}". Currently, it seems that the getPropertyNames callback is ignored completely, causing new properties set on the object to not show up the above loop iteration.
Reverting the patch from bug #29170 seems to fix the issue, though I'm not sure which part of the patch is relevant

A small test case that demonstrates the problem would make this trivial to confirm and investigate.

Sigh, still no test case :-/

Hey Oliver
I attempted make a test case for this in testapi.js, but haven't been able to replicate it yet using the "MyObject" code. Once I get a free moment I'll try and nail it down so we can have a good starting point :)
