It seems that Rex Commen plugin is causing some problems if you export to Cordova and use XDK. This is what I experienced:
1. My game (Take Down Zombies) did not work in XDK's emulator.
2. I did not know why. So I started to remove stuff from my project.
3. A lot of "Remove some stuff, Export, See if emulator works in XDK"
4. When I remove the Rex Comment object, then suddenly the emulator in XDK worked just fine.
I like the Rex Comment. It is really usefull. I hope this issue will be fixed. Can anyone perhaps verify my experience?
I just want to pas on this info.
