I found some issue like this in google
https://lists.tizen.org/pipermail/general/2013-April/002026.html
In my case, I also have javascript code to connect server and get data using Ajax.
The code which was working well in 2.1 sdk is not working after update version 2.2.
I installed it after I uninstalled 2.1sdk using sdk manager.
But, I don't think it is ajax problem cuz I tested some ajax sample code in 2.2 version.
It is not server problem and ajax code error. I checked it. That works in 2.1 sdk.
Anybody who have same problem and solve it ?
What do you think about this problem ?
Thanks,
Jenny
