I mis-read your description of the events. It sounded as if you were calling
a function that was not associated with an object, but if that function is
getting added to your object via a mixin then I see no reason why it
shouldn't work especially if you can 'see' the object with the FireBug call.
There must be a bug in the way the mixin is adding the code. If you place a
simple alert in that function does it get executed? What if you place the
alert after the three message calls? Does the call to this.error actually
die or is it dying in the first .info call?
I have a feeling that someone from the core team is going to have to look at
it in this case, as in my opinion your code should work.
