[Wicket-user] Onsubmit giving error? Missing model?

Tue, 28 Feb 2006 02:31:36 -0800 

Hi
 
Im having some trouble getting my onsubmit to work, looking at one of the 
simple examples it looks like im doing the right thing(ive been looking at 
http://www.wicket-library.com/wicket-examples/signin).
 
So hints on what im doing wrong and possible howto fix it will be much 
appreciated.
 
Ive attached my HTML file my java file and the error page.
 
Regards Nino
