[Seaside] Problem smalltalk code

[Johan Brichau]

Changing the selection in the scroll list does not submit the form automatically. You either need to have an explicit submit button, which will trigger the callbacks on the server-side, or you need to make the form submit on the 'change' event of the scroll list.

If you want the form to submit when changing the selection in the scroll list, you can use the jQuery ajax serialize functionality like this:

html select
		list: ...
		callback: ....
		onChange: (html jQuery ajax serializeForm)
