#287 ✓invalid

"Events" partially broken in IE (invalid)

Reported by sorccu | August 1st, 2008 @ 11:24 AM | in 2.0 (closed)

"this" in class events seems to be mapped to the $events[type] array in IE. In other browsers it is properly mapped to the Class itself. This ends up breaking at least Drag.Move in IE:

		// Drag.Move.prototype.initialize:
		this.addEvent('start', function(){
			this.checkDroppables(); // errors in IE
		}, true);

Here's a simple testcase:

new (new Class({
	Implements: Events,
	initialize: function() {
		this.t = 6;
		this.addEvent('fail', function() { alert($type(this) + '.t = ' + this.t) });


"object.t = 6" in good browsers

"array.t = undefined" in IE

    • Title changed from “"Events" partially broken in IE” to “"Events" partially broken in IE (invalid)”
    • Assigned user cleared.

    I am no longer able to reproduce this, even though at the time I tested this with both IE6 and IE7 and both failed (using an uncompressed 1.2.0-release made with Builder). What actually caused the error remains a mystery, but you may close this ticket for now.
