:-) i think i don't express my question accurately. i use PatternValidator to
validate fax number, the fax number is optional, that is , user don't need to
input the value, but if he/she inputed something, it must match the pattern.
Wicket doesn't has a required property for PatternValidator (and all other
validators), so when i keep the fax number field blank, the validation failed
too, it's not my original idea.
