		"description": "Although it is not stated in the [removeEventListener|http://developer.appcelerator.com/apidoc/mobile/latest/Titanium.UI.Window.removeEventListener-method.html] documentation, the method's second argument (a callback) is mandatory. Unless there is a good reason, please make it optional.\r\n\r\nThere is also an inconsistency between Android and iOS (Android simply requires an object, whereas iOS requires an anonymous function), as demonstrated using following code:\r\n\r\n{code:lang=javascript}\r\nvar win = Ti.UI.createWindow({\r\n\tbackgroundColor: '#000',\r\n\texitOnClose:true\r\n});\r\n\r\nvar button = Ti.UI.createButton({\r\n\ttitle: 'Click to log events!',\r\n\theight:80,\r\n\twidth: 300\r\n});\r\n\r\nwin.add(button);\r\nwin.open();\r\n\r\nbutton.addEventListener('click', function(){\r\n\tTi.API.info('Button click event fired');\r\n\twin.fireEvent('testWinEvent');\r\n\tTi.App.fireEvent('testTiAppEvent');\r\n});\r\n\r\nwin.addEventListener('testWinEvent', function(){\r\n\tTi.API.info('testWinEvent event fired');\r\n});\r\nTi.App.addEventListener('testTiAppEvent', function(){\r\n\tTi.API.info('testTiAppEvent event fired');\r\n});\r\nwin.removeEventListener('testWinEvent'); // this will generate an exception\r\n// win.removeEventListener('testWinEvent', {}); // this will work on android but generate an exception on iOS\r\n// win.removeEventListener('testWinEvent', function(){}); // this will work on both platforms without generating an exception\r\nTi.App.removeEventListener('testTiAppEvent',function(){});\r\n{code}\r\n\r\nIf the second argument is omitted on Android, the following exception is generated:\r\n\r\n{code}\r\nD/KrollContext(  637): (kroll$1: app://app.js) [117,656] Running evaluated script: file:///android_asset/Resources/app.js\r\nE/KrollMethod(  637): (kroll$1: app://app.js)
