java.lang.NullPointerException in data retrival


0

In my application I am retrieving records of products from a list.

When I wrote code to bind product discount percent details I got this error.

java.lang.NullPointerException

This happened earlier randomly on my site 1 out of about 100 cases and the error was resolved w/o making any change in code.

Now the frequency of this error have increased. Can anyone have view to solve this?
