Thank you, Denny. Yes, I understand that it is done like this, but I am actually trying to discuss the consistence of the framework design. Is there any specific reason that 'select' event handler works differently from any other event handler? If yes, then why Submit component generates exactly 'select' event? What exactly we are selecting when pressing a Submit button? Why its event is not 'action'?

The error message is clear. This type of event does not support return values from event handler methods. Please take a look at http://wiki.apache.org/tapestry/Tapestry5HowToUseForms Dealing with multiple submits Capter.
