The exception happens before validation.
I aksed the same question before and I didn't get a clean solution yet, so
far, if you define it as a java.sql.Timestamp, you have to provide an input
in yyyy-mm-dd hh:mm:ss.fffffffff format
Did you try beanDef?
Or maybe you can change the default RequestProcessor to your own
RequestProcessor and when populating the actionForm form-bean, use
LocaleBeanUtil instead of BeanUtil, but I haven't done that yet.
Please let me know when you got something done since I am also struggling
with this. Thanks
