[Seaside] jquery serialization question

[Bob Arning]

Probably wouldn't hurt to offer more detail, but here is a runnable 
version of your snippet that seems to happen once per click.

renderContentOnLarry1: html

     | fromCallback counter |

     counter _ 0.
     html form: [
         html textArea
             id: #postStatusTextArea;
             callback: [ :value | counter _ counter + 1. fromCallback _ 
value.];
             value: 'initial text'.
         html div
             onClick: (html jQuery ajax serializeForm
                 onSuccess:
                     (html jQuery ajax
                         script: [ :s |
                             s add: ((html jQuery: #postStatusTextArea) 
value: counter asString,' [',fromCallback asString,']').
                             s add: ((html jQuery: #activityStream) 
prepend: counter asString) ]) );
             with: 'click here'
     ]

My guess would be that you used a submitButton that forced a 
serialization/callback in addition to the explicit one you included.

Cheers,
Bob
