		"description": "When you attach an object to a Window on iOS the object is immutable, yet on Android it works fine.  For example, win.myCustomObject = { id: val } works as expected.  However, when you then try and change a value within that object, the changes are never made i.e. win.myCustomObject.id = newVal, the id stays the same.\r\n\r\nCode example requires two files:\r\n\r\n{code:lang=javascript|title=app.js}\r\nvar win = Ti.UI.createWindow({\r\n  backgroundColor: '#000',\r\n  url: 'window_object_win.js',\r\n  layout:'vertical'\r\n});\r\n\r\nwin.data = {\r\n  text: 'Initialized'\r\n};\r\n\r\nwin.open();\r\n\r\nwin.addEventListener('modifyData', function() {\r\n  win.data.text = 'This should be updated if this object is mutable';\r\n  win.fireEvent('dataUpdated');\r\n});\r\n\r\nwin.addEventListener('replaceData', function() {\r\n  win.data = { text: 'If the data has changed now then replacing the entire data object works ' };\r\n  win.fireEvent('dataUpdated');\r\n});\r\n{code}\r\n\r\n{code:javascript|title='window_object_win.js'}\r\nvar modifyButton = Ti.UI.createButton({\r\n  title: 'Modify window .data object',\r\n  top: 60,\r\n  width: 250,\r\n  height: 80\r\n});\r\n\r\nvar replaceButton = Ti.UI.createButton({\r\n  title: 'Replace window .data object',\r\n  top: 60,\r\n  width: 250,\r\n  height: 80\r\n});\r\n\r\nvar label = Ti.UI.createLabel({\r\n  color: '#FFF',\r\n  top: 20,\r\n  height: 200\r\n});\r\n\r\nTi.UI.currentWindow.add(modifyButton);\r\nTi.UI.currentWindow.add(replaceButton);\r\nTi.UI.currentWindow.add(label);\r\n\r\nmodifyButton.addEventListener('click', function() {\r\n  Ti.UI.currentWindow.fireEvent('modifyData');\r\n});\r\n\r\nreplaceButton.addEventListener('click', function() {\r\n  Ti.UI.currentWindow.fireEvent('replaceData');\r\n});\r\n\r\nvar counter = 0;\r\n\r\nvar updateLabelFromData = function() {\r\n  label.text = 'Text (' + counter++ + ' presses) = ' + Ti.UI.currentWindow.data.text;\r\n};\r\n\r\nTi.UI.currentWindow.addEventListener('dataUpdated', updateLabelFromData);\r\n\r\nupdateLabelFromData();\r\n{code}\r\n\r\nTo replicate this issue with this code example, load up the app, click on the bottom button (to modify values) and you will see that the value does not change.  However, if you click on the button above that which replaces the entire object on the window, it works fine.  On Android both buttons work as expected.",
