Mick, I noticed the same thing with our custom validator the other day. My
solution was to:
1. Use org.apache.struts.action.ActionMessages instead of
org.apache.struts.action.ActionErrors in the validator/@methodParams
2. Change your custom validator's method signature to use ActionMessages
instead of ActionErrors.
Best,
Tim
