		"description": "h3. Issue \r\n\r\nIn SDK 3.3.0 and higher when a tableView is scroll and the remove from the window and then added again to the window the scroll position is lost and restored to the original starting position, in SDK 3.2.X  when  doing this the tableView keeps the original position\r\n\r\nh3. Steps to repro\r\n\r\n1. Run test code \r\n2. Scroll the table\r\n3. Click on a row\r\n4. Click on the \"Go Back\" button\r\n\r\nExpected Result:\r\nThe tableView will be displayed again with the last scroll position \r\n\r\nActual Result:\r\nThe tableView is displayed with the original scroll position (Y value:0)\r\n\r\nh3. Test Code\r\n\r\n{code}\r\nTitanium.UI.setBackgroundColor('#000'); \r\n\r\nvar win = Titanium.UI.createWindow({ \r\ntitle:'Tab 1', \r\nbackgroundColor:'#fff' \r\n}); \r\n\r\nvar mainView = Ti.UI.createView({ \r\ntop: 45 \r\n}); \r\n\r\nvar tableView = Ti.UI.createTableView(); \r\n\r\nvar rows = []; \r\nfor (var i = 0; i < 40; i++) { \r\nrows.push(Ti.UI.createTableViewRow({ \r\ntitle: 'Row ' + i \r\n})); \r\n}; \r\n\r\ntableView.setData(rows); \r\n\r\ntableView.addEventListener('click', function(e) { \r\nmainView.add(anotherView); \r\nmainView.remove(tableView); \r\n}); \r\n\r\nvar anotherView = Ti.UI.createView({ \r\nlayout: 'absolute' \r\n}); \r\n\r\nvar backButton = Ti.UI.createButton({ \r\ntitle: 'Go back' \r\n}); \r\n\r\nbackButton.addEventListener('click', function(e) { \r\nmainView.add(tableView); \r\nmainView.remove(anotherView); \r\n}); \r\n\r\nanotherView.add(backButton); \r\n\r\nmainView.add(tableView); \r\nwin.add(mainView); \r\n\r\nwin.open(); \r\n{code}\r\n\r\nh3. Workaround\r\n\r\nIn order to keep the las position its possible to use e.firstVisibleItem for android and  e.contentOffset for iOS in order to keep a similar effect.\r\n\r\n{code}\r\nvar win = Titanium.UI.createWindow({ \r\ntitle:'Tab 1', \r\nbackgroundColor:'#fff' \r\n}); \r\n\r\nvar mainView = Ti.UI.createView({ \r\ntop: 45 \r\n}); \r\nvar tableView = Ti.UI.createTableView(); \r\n\r\nvar rows = []; \r\nfor (var i = 0; i < 40; i++) { \r\nrows.push(Ti.UI.createTableViewRow({ \r\ntitle: 'Row ' + i \r\n})); \r\n}; \r\n\r\ntableView.setData(rows); \r\n\r\n\r\n\r\ntableView.addEventListener('click', function(e) { \r\nmainView.remove(tableView); \r\nbackButton.visible=true; \r\n}); \r\n\r\n\r\n\r\nvar backButton = Ti.UI.createButton({ \r\ntitle: 'Go back', \r\ntop:10, \r\nvisible:false \r\n}); \r\nvar pos,scroll=false; \r\n\r\nbackButton.addEventListener('click', function(e) { \r\nif(Ti.Platform.osname == 'android'){ \r\ntableView.scrollToIndex(pos); \r\n}else{ \r\ntableView.scrollToTop(pos.y,false); \r\n} \r\nmainView.add(tableView); \r\n\r\nbackButton.visible=false; \r\n}); \r\n\r\n\r\ntableView.addEventListener('scroll',function(e){ \r\nif(Ti.Platform.osname == 'android'){ \r\npos = e.firstVisibleItem; \r\n}else{ \r\npos = e.contentOffset; \r\n} \r\nTi.API.info(e.firstVisibleItem); \r\n}); \r\n\r\nwin.add(backButton); \r\n\r\nmainView.add(tableView); \r\nwin.add(mainView); \r\n\r\nwin.open();\r\n{code}\r\n",
