[Seaside] Jquery submit loads page

[Norbert Hartl]

Maybe I'm just too tired to get it straight. I have

html form with: [
	html submitButton 
		onClick: (html jQuery ajax serializeForm );
		with: 'foo' ]

and if I click the button I get the ajax request and afterwards the page is loaded.

What could I've forgotten?

thanks,

Norbert
