I'm using Squeak and SeasideAsync and Scriptaculous

I'm adding liveCallbackYear to dateInput.

Yes I added the following:
| uri id |
id _ self ensureId.
uri _ canvas urlForLiveAction:
[:event :h | liveBlock
value: event value
, (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!
