Random crashes on TableView delete event
I'm running into random crashes whenever I delete a row from a tableView.
The tableView consists of 2 sections and is being used to hold a form.
-Section: General
---Textfield
---Textfield
-Section: List
---Textfield - Button
[---TableViewRow]*
- =a generated list of items, all exact the same like this one using the following function:
function createRowFromData(current){ var nextItemRow = Titanium.UI.createTableViewRow({title: current.name}); nextItemRow.touchEnabled=true; nextItemRow.hasCheck = current.checked; return nextItemRow; }
Deleting crashes the app 3 times out of 10.
I can't figure out what this is related to at all.
iPhone simulator just quits the app, and this is all I'm left with:
[DEBUG] Session did end with error (null)
[INFO] Application has exited from Simulator
I tried to see if it's related to my delete handler (which reflects the deleted row action to an array that holds the data of the table) using an info() trace but I never get to see it, so I presume the app crashes before it even gets to that statement.
At one point I decided to see if the delete handler was in any way involved in this, so I just commented it out. With enough patience I got the app to quit again, this time providing a stack trace.
[ERROR] The application has crashed with an unhandled exception. Stack trace:

terminate called after throwing an instance of 'NSException'
At this point I have no clue what is happening, or what to look for.
Is there anybody who knows what I'm doing wrong, or what this migh be related to?
Any help would be highly appreciated.

Did you figure this out? I'm running into the same thing, but I crash consistently on a tableview row delete.
-
I started having the same problem but only on Android. The iPhone version deletes properly. Have you found any solution?

I have the same problem but found that the app only crashes when I delete the first row in the table.
Does anyone have any solutions for this?

I had a "similar" situation. My app would crash when I closed a window I had created with createWindow(..) if I had added a tableView with rows to the window. I fixed the issue by simply calling win.remove(myTableView).. Titanium has COUNTLESS issues on android, I have spent the last 2 weeks porting an IOS app I wrote with titanium to android..
