I just looked at the code and it looks like I broke
backwards compatibility when I added the methods that
return objects instead of boolean values. The
validateDate method used to default to true and only
validate the field if it wasn't blank or null. So if
the field was blank, date validation was skipped but
'true' was returned so an error message wasn't
generated. Now the method returns null which is being
interpretted as a failure so an error message is being
created. We might need to remove this functionality
for now and just use the boolean methods at least
until after the Struts 1.1 release. I'll think if
there are any other ways to do this and keep it
backwards compatible.
