I'm using Squeak and SeasideAsync and Scriptaculous

I'm adding liveCallbackYear to dateInput.

Yes I added the following: 

liveCallbackYear: liveBlock
	| uri id |
	liveBlock fixTemps.
	id _ self ensureId.
	uri _ canvas urlForLiveAction: 
		[:event :h | liveBlock
			value: event value
			value: h].
	self session 
		addLoadScript: 
			'liveSearch('
				, (id asString, '-year') printString
				, ','
				, (canvas encode: uri asString) printString
				, ')'.

I can see that it creates the date but what triggers the hiddenInput
callback?  It appears to work without submitting the form.

Thanks for your help!
