Description
This kind of problem has already been reported in ticket 5862 and the problem has been fixed for the 'data' object but the problem remains for sub objects contained in 'data' object:
If there is a key named "length" in an sub object contained in the 'data' object, then the data are broken as the value of "length" is used to redefine the "array" length..
jQuery.ajax({
type: 'POST',
url: url,
data: {'test': {'length': 3, 'foo': 'bar'} },
success: ...
Data posted are:
test[0] undefined test[1] undefined test[2] undefined

culprit. Should change that to use a for loop instead of $.each.

That's because of $.each() that think: "ok, you have a length property, then you are an array".
I would like to tell it: "well, no, it's not an array, it's an object that describe something long enough to have a length property"...
But it would for sure respond: "So it's an array-like". Luckily jquery functions do not speak.
