I read the comment (copied below) and was a little confused:
SUAjax>>callback: aBlock value: anObject
"Register aBlock as a secondary callback. anObject is interpreted as
server and passed into aBlock. Multiple secondary callbacks can be
defined with one receiver."
I took this to (incorrectly) mean that anObject is serialized to a
json format, and is included as a string in the post parameters. This
str := SUStream new nextPutAll: 'myMap.toJson()'.
onClick: (html request
callback: [ :value | self updateModel: value ] value: str );
with: 'SURequest example'
So my final question is do you need the primary callback at all?
