		"description": "the following example allows for multiple open/close of the tabGroup - and each time, the number of proxys increase and are never reduced. Also, the actual references (TiUIView, TiUITabController, TiUIWindow) increase and never reduce.\r\n\r\n\r\nExample Code:\r\n// app.js\r\n \r\nvar oxi={};\r\nTi.include('appframework.js');\r\n \r\n(function(){\r\n    var win = Ti.UI.createWindow();\r\n    var mainUI;\r\n\r\n    function terminateUI() {\r\n        mainUI.close();\r\n        mainUI = null;\r\n        Ti.App.removeEventListener('terminateUI', terminateUI);\r\n        win.open();\r\n    };\r\n \r\n    function launch() {\r\n        win.close();\r\n \r\n        mainUI = oxi.ui.createMainUI();\r\n        Ti.App.addEventListener('terminateUI', terminateUI);\r\n        mainUI.open();\r\n    }   \r\n \r\n    win.addEventListener('click',launch);\r\n    win.open();\r\n})();\r\n \r\n// appframework.js\r\n \r\n(function(){\r\n    oxi.ui = {};\r\n \r\n    oxi.ui.createMainUI = function() {\r\n        var tabGroup = Ti.UI.createTabGroup();\r\n \r\n        var tab1 = Ti.UI.createTab({\r\n            title:'Library',\r\n            window: Ti.UI.createWindow({\r\n                navBarHidden: true\r\n            })\r\n        });\r\n \r\n        var tab2 = Ti.UI.createTab({\r\n            title:'Settings',\r\n            window: Ti.UI.createWindow({\r\n                navBarHidden: true\r\n            })\r\n        });\r\n \r\n        tab1.window.add(Titanium.UI.createView({\r\n            backgroundColor: '#ffc'\r\n        }));\r\n \r\n        tab2.window.add(Titanium.UI.createView({\r\n            backgroundColor: '#ffc'\r\n        }));\r\n \r\n        tabGroup.addTab(tab1);\r\n        tabGroup.addTab(tab2);\r\n \r\n        tab1.window.addEventListener('click',function(e){\r\n            Ti.API.info('clicked on win1');\r\n            Ti.App.fireEvent('terminateUI');\r\n        });\r\n \r\n        return tabGroup;    \r\n    };\r\n})();\r\n\r\nBy changing the terminateUI() function to the following, all references and proxies are removed, except the one for win (intentional, as it is not set to null) and the one for mainUI (unintentional, as it is set to null explicitly after closing the tabGroup):\r\n\r\nfunction terminateUI() {\r\n        for (var tab=mainUI.tabs.length-1;tab>-1;--tab) {\r\n            mainUI.removeTab(mainUI.tabs[tab]);\r\n        }\r\n        mainUI.close();\r\n        mainUI = null;\r\n        Ti.App.removeEventListener('terminateUI', terminateUI);\r\n        win.open();\r\n};\r\n\r\nFor subsequent runs (the code allows for open/close multiple times of the tabGroup) the proxy for the tabGroup is cleared - however, the FIRST proxy is never disposed of.",
