fireEvent takes two arguments:
the event ('callback')
args (an object, or an array)
the args object is passed to your function as you would expect, but consider
these two examples:
this.addEvent('foo', function(number) {
alert(number);
});
this.fireEvent('foo', 1); //alerts "1"
this.addEvent('foo', function(x, y) {
alert(x + ' / ' + y);
});
this.fireEvent('foo', [1, 2]); //alerts "1 / 2"
When you pass an array, those become arguments. If you want an array to BE
an argument you need to wrap it:
this.addEvent('foo', function(arr) {
alert(arr[0] + '/' + arr[1]);
});
this.fireEvent('foo', [[1,2]]);
