I followed your advice and it works.
If you try to find solution for the problem, another hint :I am using castor 0.9.9.1.
Thanks for your reply

Jakub-
I've also observed this problem in the past few months with Castor.
Unfortunately I haven't had time to track down a source of the
problem. One work-around you can try is to define defining the type
attribute for the value as java.lang.Object. It's hackish, but I
think I snuck some things by Castor doing that.
And thanks for the detailed message, it will be helpful when I get
around to investigating the problem.
