Test Case\r\n\r\nEvery time the button is clicked, one extra \"blurListener\" is added, each resulting in a message on log. Thus, the removeEventListener is not working.\r\n\r\n\r\n{code:lang=javascript|title=app.js}\r\nTi.UI.setBackgroundColor('#000');\r\n\r\nvar win1 = Ti.UI.createWindow({\r\n\ttitle: 'Win1',\r\n\tfullscreen: true\r\n});\r\n\r\nvar win2 = Ti.UI.createWindow({\r\n\ttitle: 'Win2',\r\n\tfullscreen: true\r\n});\r\n\r\nvar btn = Ti.UI.createButton({\r\n\ttitle: 'Button',\r\n\ttop: 10\r\n});\r\nwin1.add(btn);\r\n\r\nvar lbl = Ti.UI.createLabel({\r\n\ttext: 'Label',\r\n\ttop: 10\r\n});\r\nwin2.add(lbl);\r\n\r\nvar i = 0;\r\nvar blurListener = function() {\r\n\tTi.API.info('blurListener: ' + (i++));\r\n\twin1.removeEventListener('blur', blurListener);\r\n};\r\n\r\nbtn.addEventListener('click', function() {\r\n\twin1.addEventListener('blur', blurListener);\t\r\n\t\r\n\tTi.API.info('---');\r\n\twin2.open({\r\n\t\tanimated: true\r\n\t});\r\n});\r\n\r\nwin1.open();\r\n{code}\r\n\r\nh3. Workaround\r\nYou can solve the problem by overriding the addEventListener and removeEventListener prototypes of the Titanium.UI.Window objects. Just insert the code below into the app.js.\r\n\r\n{code:javascript}\r\n(function() {\r\n\tif (Ti.Platform.name == 'android') {\r\n\t\tvar _addEventListener = Ti.UI.Window.prototype.addEventListener;\r\n\t\tvar _removeEventListener = Ti.UI.Window.prototype.removeEventListener;\r\n\t\t\r\n\t\tTi.UI.Window.prototype._eventListener = function(e) {\r\n\t\t\tif (typeof e.source == 'undefined') return;\r\n\t\t\tif (e.source.toString() != '[object TiBaseWindow]') return;\r\n\t\t\tvar listeners = e.source._eventListeners[e.type];\r\n\t\t\tfor (var i=0; i<listeners.length; i++)\r\n\t\t\t\tlisteners[i](e);\r\n\t\t};\r\n\t\t\r\n\t\tTi.UI.Window.prototype.addEventListener = function(type, func) {\r\n\t\t\tif (!this._eventListeners) this._eventListeners = {};\r\n\t\t\tif (typeof this._eventListeners[type] == 'undefined') {\r\n\t\t\t\tthis._eventListeners[type] = [];\r\n\t\t\t\t_addEventListener.call(this, type, this._eventListener);\t\r\n\t\t\t}\r\n\t\t\tthis._eventListeners[type].push(func);\r\n\t\t};\r\n\t\t\r\n\t\tTi.UI.Window.prototype.removeEventListener = function(type, func) {\r\n\t\t\tif (typeof this._eventListeners[type] != 'undefined') {\r\n\t\t\t\tvar listeners = this._eventListeners[type];\r\n\t\t\t\tfor (var i=0; i<listeners.length; i++) {\r\n\t\t\t\t\tlisteners.splice(i, 1);\r\n\t\t\t\t\tbreak;\t\r\n\t\t\t\t}\r\n\t\t\t}\r\n\t\t};\r\n\t}\r\n})();\r\n{code}\r\n\r\nh2. Logs\r\n\r\nThe output of the above script after 3 button press and back:\r\n{code:lang=none|title=console}\r\n[INFO]\t---\r\n[INFO]\tblurListener: 0\r\n[INFO]\t---\r\n[INFO]\tblurListener: 1\r\n[INFO]\tblurListener: 2\r\n[INFO]\t---\r\n[INFO]\tblurListener: 3\r\n[INFO]\tblurListener: 4\r\n[INFO]\tblurListener: 5\r\n{code}",
