Unable to pass event object when firing a native key(up|down) event

[afbobak]

Basically I'm trying to do this:

$("input").fire("keydown", {
  type: "keydown",
  keyCode: 191
});

If I read the code correctly it should fix the half-baked event I pass in as a second argument and then go through all the listeners and call the handler with the fixed event.

In practice fire() prepends the boolean false (line 517) to the arguments which then gets passed to the nativeHandler's handler (line 334) but the handler expects the argument "event" as the first argument, which now is always false and thus always fixes the wrong event object.

When I change the nativeHandler's handler to

handler = function (f, event)

then things work with no apparent side-effects.

What's the reason the false prepended?

The 'args' are meant to be additional arguments to the event handler rather than the Event object itself. There is scope though to implement proper Event object handling but it's not in there at the moment.
It's possible that we could squeeze something into the upcoming 1.0 release since it would likely be an API breaking change, or at a minimum we could make room for it in 1.0 for implementation in 1.1 perhaps.
If you feel like contributing, the 1.0 code is in the 0.5-wip branch, there's a write-up here about what's in it and the API breakages: http://rod.vagg.org/2012/08/bean_v1/
