Problem
When using Ti.UI.TableView.updateRow, you can no longer call Ti.UI.TableView.deleteRow without causing an error.

Steps to reproduce
Make a project with the below app.js.
Click the 'update rows' button (this will only update row 0)
Click the 'delete rows' button
#* Notice that the simulator exits with the previous error message.
#* - SDK 1.8.2 will not exit but give a similar message. It will only delete row 1 and leave row 0 (the updated one)
var win1 = Ti.UI.createWindow({});
var data = [{title:'Row 1'}, {title:'Row 2'}];
var table = Ti.UI.createTableView({data:data});
win1.add(table);
var btn1 = Ti.UI.createButton({
title:'delete rows',
width:120,
height:50,
left:10,
bottom:0
});
btn1.addEventListener('click',DoBtn1Click);
win1.add(btn1);
var btn2 = Ti.UI.createButton({
title:'update rows',
width:120,
height:50,
right:10,
bottom:0
});
btn2.addEventListener('click',DoBtn2Click);
win1.add(btn2);
function DoBtn1Click()
{
for (var row=(table.data[0].rowCount-1); (row >= 0); row--)
table.deleteRow(row);
}
function DoBtn2Click()
{
table.updateRow(0, table.data[0].rows[0]);
}
win1.open();
Hello, tested in 1.9 CI build, it's working fine. You can get the buidl from this page: http://builds.appcelerator.com.s3.amazonaws.com/index.html choose the master branch, and copy the url for your platform, and then from the help menu in Ti Studio, just install from SDK. Best, Mauro
Mauro, When I choose the "master" branch, I get the 2.0 SDK downloads. I don't see a choice for 1.9. I did however download the 2.0 SDK and tried it with my test application that I provided in the code and it still gives me the same error. I know that the fix may not be merged into the 2.0 code yet, but is there a way you could merge the fix into 1.8.2? Also, I have simplified the steps to re-create this issue. Jon
Verified fix on SDK 2.0.0.v20120325213306. Thanks!
