Is Blackberry Storm 2 backwards compatible with Blackberry JDE 4.5? We have an application built using JDE 4.5 which was already delivered to the customer. The customer has problems with running the application on Blackberry Storm 2. Is this a backwards compatibility issue? I have a BB Curve which runs 5.0 OS and it can load and run the app without problems.

Did your customer tell you what problem they are having?

They cannot enter the username into the login field. The login field is created as Edit Field - instance of net.rim.device.api.ui.component.EditField:
_txtUserID = new EditField("Username: ", "", 15, EditField.NO_NEWLINE | EditField.FIELD_RIGHT);

Backwards compatibility will cause annoyances but it should still work.
Is the user able to select the field (does it get focus)? If not then that would be your problem (I would guess you are using a custom Manager).
If it is using a standard Manager then maybe the user doesn't understand how to navigate in Backwards compatibility mode (the screen acts like a giant trackpad).
Now, since you said that it works on 4.5 (and touch support wasn't until 4.7) I suspect that the Manager isn't the problem. Instead I would hope that the user can select the field (thus invoking focus). All that Backwards compatibility mode does is keep the screen in portrait mode, bring up (and keep up) the virtual keyboard, and treat the screen area as a large trackpad (as mentioned before).
