Sorry to hear it didn't work. I am having my own share of problems with that ExpressionValidator, and I found one useful suggestion in the following doc: http://www.opensymphony.com/xwork/wikidocs/ExpressionValidator%20Tips.html Look for the section entitled "Use the validation message for debugging".
I hope this may help you identify the problem! 2008/8/2 Hrvoje Ban <[EMAIL PROTECTED]> > I tried that, I even renamed function to getUsernameAvailable(), but > it didn't help. >
