Can someone please help me on the below issue:

In my server side i.e. Apex class I'm querying an object with few fields and then I'm passing it to the client side i.e js.helper. I got the list of records for that object, but the field which has null value is not at all appearig in the list of object records passed by the Apex class. That field will be present if it's value is not null and it doesn't appear if it's value is null.

But I want to get that field even it's value is null when it's passed from Apex to J's.helper as a object property in the helper.
