Class 'net.rim.device.api.ui.Ui Enginelnstance' not found

I am having an app which supports OS >= 5.0 and it installs and runs normally on os 5,6,7 devices but App World rejected it saying that it show "Class 'net.rim.device.api.ui.Ui Enginelnstance' not found" error when they install it on 8520 device.

 

I tried on 8520 simulator and another real os 5 device and it runs ok so my question is why would such a thing happen?

I am signing the app normally and I am sending them the content of the deliverables folder with standard and OTA installations. I am wondering if I am doing something wrong.

Those types of errors are usually caused by creating the application in a version of BlackBerry Java SDK that is higher than the version of BlackBerry OS running on the BlackBerry Smartphone.  Refer to this link for more information.

 

Appropriate version of the BlackBerry JDE and BlackBerry Java SDK
