Samuel, I ran into the same problem (as reported in JIRA). Replace the ParametersInterceptor in Xwork with the one attached. Note that this patch will only work with wrapper objects. Primitive values are still failing.

Hi, Im using a number field at my form, but I can't leave it blank because I get an exception. Is that right? In time, another problem is that when using a RangeValidator it acts as if that field is required ... should be nice to add a parameter to the validator to tell him if a null value is ok for you , shouldn't?
