Sorting on number field db4o Android

Question

I am using db4o database for storing data in my Android application. I want to sort objects on Number field.

But, when I use query.descend("number").orderDescending();, I am getting NullPointerException.

Why?

if its giving null pointer exception that means it is not getting the view — Hassaan Rabbani, Oct 25 '13 at 13:06
in short the pointer is not actually pointing at the NUMBER field. show us the code — Hassaan Rabbani, Oct 25 '13 at 13:17

Finally, solved problem.

Actually the problem was number was stored in format double exponential. Then I converted the number in long and the problem is gone :-)
