Hey Guys,
I hope somebody can help us wrapping our head around the below described problem and how to debug it or how to find a solution for it. I'll try to give as much information as possible.
What is the Problem?
Our customer got multiple customer/user reporting that their mobile version of the Internet Explorer on Windows Phone 8.1 crashes when trying to login to the website. The problem is permanent, happens all the time and the website is in a unusable state for the customers with Windows Phones.
This problem happens on no other operating system like iOS, Blackberry, Android, Jolla OS, Unix, Ubuntu or any other browser, it seems to just be a Windows Phone together with the mobile Internet Explorer problem.
What is expected?
Mobile Internet Explorer shouldn't crash like on all other OS and browsers.
How to reproduce?
Go to mono.mobility.ch/mrs and try to login (441073/366633) or (459521/000000) (it's a test system)
Additional Information
* On Nokia Lumia Amber (Windows Phone 8) everything works.
* On Nokia Lumia Black (Windows Phone 8) we don't know (we do not have a device with this version installed) but probably it works
* On Nokia Lumia Cyan (Windows Phone 8.1) it doesn't work
* On Nokia Lumia Denim (Windows Phone 8.1) it doesn't work
We then tried to investigate a bit:
* The form uses method post
* We don't try to open a new tab with _blank
* We don't try to open a new window with _new
* We don't try to write to the console (from what I've seen) (which maybe could've lead to a NPE in the mobile IE because the console is not there/initialized)
* We tried to delete cache, history, restart the phone and do a soft reset etc.
I'd appreciate help on this a lot, if you need more information please tell me what information you need and I'll try to provide them to whomever.
Best Regards
Thomas Steinbrüchel
