Subject pluggable arg0 not plugging (newbie)
Date Tue, 04 Jan 2005 14:49:03 GMT
Hello, 

I cannot seem to get the validator to plug args into my messages. 
Everything else works (LogonForm.java/LogonAction.java,...).

When I run this basic test and click Submit with 3 empty fields, I get: {0} is required!{0}
is required!{0} is required! 

Maybe somebody could kindly point out something obvious that I 
missed/don't (yet) get?!

Thanks --Mike
