[news.eclipse.rt.eclipselink] Re: Negative Ids

HI James,
thank you.
I will vote for that logged bug.

I could use Integer id
instead of int. The problem is that I use persistence also for my JSP 
page....I
need to make persistent value set by user in form on jsp page. I use 
java bean
and they work with primitive types  (int, ..string,...array of 
primitives...).
If I use Integer, I need always make control to cast int type to integer 
(into
get methods).
I prefer they solve the bug :-)
