Yes this was fixed in Validator 1.2.0:

The latest version of Validator is 1.3.0 - it is compatible with
Struts 1.2.9, but I haven't tried it with Struts 1.2.7 and can't off
the top of my head remember if there were any compatibility changes
(some validator bugs were fixed in 1.2.8). Both Struts 1.2.8 and 1.2.9
were primarily fixes for security issues, so it would probably be a
good idea to upgrade your version of Struts anyway.

Below are details of Struts and Validator versions and upgrade notes for Struts
