Re: How to dynamically show and hide the null values of a response?

[Sergey Beryozkin <sb...@gmail.com>]

I guess I misunderstood the question,

I see that you'd like nulls being reported without having to set a JAXB 
nillable property, so no we can't do it. What is possible is to set a 
nillable property but then configure JSONProvider to ignore xsi:nil && 
xsi:type attributes by setting its 'writeXsiType' property to false;

Cheers, Sergey
