It'll \"hang\" on the splash screen.\r\n# In the log, copy the the \"chrome-devtools://devtools/bundled/inspector.html?...\" URL.\r\n# Open the Chrome browser and paste the copied URL.\r\n# In Chrome, select the \"Memory\" tab.\r\n# Select the \"Allocation instrumentation on timeline\" radio button.\r\n# Click the \"Start\" button.\r\n# Select the \"Sources\" tab.\r\n# Click the \"Resume script execution\" toolbar button in top-right corner. Looks like: [>]\r\n# Wait for the Titanium app to display a TableView.\r\n# Click the \"Reload\" button in the bottom-right corner of the app.\r\n# Click the Android back button.\r\n# In Chrome, select the \"Memory\" tab.\r\n# In Chrome, top-left corner, click the \"Stop recording heap profile\" toolbar button.\r\n# Under the \"Constructor\" column, expand the \"Label\" tree.\r\n# Note that 50 Labels are listed under it. These have not been garbage collected.\r\n\r\n{code:javascript}\r\nfunction createTableData() {\r\n\tvar tableData = [];\r\n\tvar maxIndex = 50;\r\n//var maxIndex = Math.floor(Math.random() * 100) + 1;\r\n\tfor (var index = 1; index <= maxIndex; index++) {\r\n\t\tvar row = Ti.UI.createTableViewRow();\r\n\t\trow.add(Ti.UI.createLabel({ text: \"Row \" + index.toString() }));\r\n\t\ttableData.push(row);\r\n\t}\r\n\treturn tableData;\r\n}\r\n\r\nvar window = Ti.UI.createWindow({ exitOnClose: false });\r\nvar container = Ti.UI.createView({\r\n\twidth: Ti.UI.FILL,\r\n\theight: Ti.UI.FILL,\r\n});\r\nvar tableView = Ti.UI.createTableView({\r\n\tdata: createTableData(),\r\n});\r\ncontainer.add(tableView);\r\nvar reloadButton = Ti.UI.createButton({\r\n\ttitle: \"Reload\",\r\n\tbottom: \"10dp\",\r\n\tright: \"10dp\",\r\n});\r\nreloadButton.addEventListener(\"click\", function(e) {\r\n\tTi.API.info(\"@@@ Reloading table data.\");\r\n\ttableView.data = createTableData();\r\n});\r\ncontainer.add(reloadButton);\r\nwindow.add(container);\r\nwindow.open();\r\n{code}\r\n\r\n*Notes:*\r\n* If a {{TableView}} is garbage collected, then its rows are correctly garbage collected as well. This is only an issue when overwriting the rows via the \"data\" property.\r\n* This is an issue for Alloy since its generated code will replace the {{TableView}} \"data\" array any time the model changes via a \"fetch\", \"destroy\", \"change\", \"add\", \"remove\", or \"reset\" event.\r\n",
