Same build is tested on a device with ios5 and multiple devices with ios6. The problem is consistent on ios6 devices, while ios5 devices work fine.
Unfortunately I can't paste a self contained example of the working code, but here's what's going on.
From one tab, another tab is set active with a window opened (some of the views and the window are earlier declared and previously used).
this is the code, but it's pretty generic if out of context...
self.open = function() {
trip_tab.open(win, {animated: false});
tabGroup.setActiveTab(trip_tab).open();
};
...
...
...
self.open();
Here's the console log:

[INFO] Application has exited from Simulator
I just installed 2.1.3 rc2 from here http://builds.appcelerator.com.s3.amazonaws.com/mobile/2_1_X/mobilesdk-2.1.3.v20120927181611-osx.zip
I was hoping the problem was this (there is in fact map used in that view/window):
TIMOB-10891 iOS 6: Repeatedly opening a tab group containing a map view crashes the application. (Known issue in RC)
(described here: http://developer.appcelerator.com/blog/2012/09/titanum-2-1-3-rc2-is-released-with-additional-fixes-for-ios-6-and-iphone-5.html )
But after updating from previous rc to rc2 the problem still exits...
Please contact me -- I'll be happy to assist with troubleshooting this.
Thank you.
Fyi, as a temporary workaround I switched the calls from trip_tab.open(win, {animated: false}); tabGroup.setActiveTab(trip_tab).open(); to tabGroup.setActiveTab(trip_tab).open(); trip_tab.open(win, {animated: false}); This solved the problem, however this is not optimal as a long term fix since there's a short flicker of a previous window in that tab now.
The fix I described above no longer works after 2.1.3 GA update.
Any news on this?
We'd be able to look at this faster with a test case, are you sure it's not possible to put one together? I don't expect you to paste your production code, but just try to re-create the problem in a new simple project. Thanks!
Sample test project which recreates the problem
The Tabgroup implemetation on 2_1_X had a bug with state retention which was fixed as part of TIMOB-10891 Run the attached sample app against 2_1_X and you'll see that opening the tabgroup a second time will close win2. Run this against master or 3_0_X CI and it should work fine (TIMOB-12244 was a bug discovered during the triage of this bug and has been fixed.) The crash happens because a window is being associated with two navControllers at the same time. Since 3_0_X and master now have proper state retention, you shouldn't have to call trip_tab.open(win, {animated: false}); if the window is already open. You could write the app along the guidelines presented in the attached app.js To workaround the bug in 2_1_X I recommend explicitly closing the window before closing the tabGroup.
Nothing to do here. State retention has been fixed in 3_0_X and master. App can be fixed with JS workaround
Tested with the attached app.js and instructions in the comment. Verified on: Studio: 3.0.1.201212181159 SDK: 3.0.0.GA, 3.0.1.v20130108154840, 3.1.0.v20130114171802 iOS Device: iOS Simulator 6.0, iPad mini (v6.0) XCode: 4.5.2 CLI: 3.0.22
still happening here, just tested it on TiSDK 3.1.0.v20130201161008, iPad 4 Gen, iOS 6. It doesn't always happen, but from time to time my app would freeze with this error. I'm planning on preparing a dummy project, don't really have time now. Just to let you guys know.
