Both options are viable. In your blog post you didn't exactly say what you
were wanting to parse the request for, I was trying to tell you that under
normal circumstances you don't need to do that, post your form and let
Seaside bind the values up to your model for you. Flash talking to the
server and saving data is not a normal circumstance.
I'd use Scriptaculous to hook some event you're interested in so when that
event occurred a callback was done to pass data back to the server using
some JavaScript to read the data from the client side element if it's a
simple value...
html div
onMouseOut: (html request
callback: [ :value | value inspect ]
value: (SUStream new nextPutAll: 'fetchFlashData()'))
If it's more complex with a bunch of fields, I'd post a form back on some
event as you state in #2...
html div
onMouseOut: (html updater
id: #someStatusIndicator ;
triggerForm: #someId ;
on: #renderStatusOn: of: self)
Or just use a request instead of updater if you don't care about showing any
feedback.
The form itself of course would be bound to instance variables of some class
and rendered with either dynamic JavaScript generated using the generated
id's of the fields so the Flash JS knows what field names to write into, or
I'd just hardcode simple manual id's to the fields and use some static
JavaScript bound to known names.
