					"body": "In the test case, when the table is scrolled, new rows are displayed on the screen so new label proxies are created. This means if the table is scrolled to the end, it needs to create 500 label proxies. That's why OOM happens.\r\nWhen the tableview has a large number of rows, the [className|http://docs.appcelerator.com/titanium/latest/#!/api/Titanium.UI.TableViewRow-property-className] property is recommended to use. If we give the same className to the rows which have the same layout, our platform can reuse those proxies and only reset the content. This will save a lot of memory and make the tableview perform much better.\r\nExample code:\r\n{code}\r\nTitanium.UI.setBackgroundColor('#000');\r\n  \r\nvar win1 = Titanium.UI.createWindow({  \r\n    title:'Tab 1',\r\n    backgroundColor:'#fff'\r\n});\r\n  \r\nvar ref_data = new Array();\r\nvar rowView=\"\";\r\nvar row=\"\";\r\nfor (var a=0; a<= 500; a++){\r\n  \r\n                 \r\n                row = Ti.UI.createTableViewRow({\r\n                \tclassName: \"myRow\"\r\n                });\r\n                row.selectedBackgroundColor = 'yellow';\r\n                row.backgroundColor = '#FFffff';\r\n  \r\n                row.height = 55;\r\n  \r\n  \r\n                ref_data.push(row); \r\n  \r\n        }\r\n  \r\nref_tableView = Titanium.UI.createTableView({\r\n    data:ref_data,\r\n    height:'auto'\r\n    //backgroundColor:'white'\r\n});\r\n  \r\nwin1.add(ref_tableView);\r\n  \r\nwin1.open();\r\n{code}",
