[Seaside] Checkbox and AJAX?

You *can* re-render just a row or even just a cell. I use the following 
to re-render a single cell:

     s1 _ html jQuery ajax
         callback: [ :value |
             value = 'undefined' ifTrue: [
                 lastCellIndex _ nil.
             ] ifFalse: [
                 lastCellIndex _ value.
                 showing at: lastCellIndex put: (showing at: 
lastCellIndex ifAbsent: [false]) not.
         value: (((html jQuery: '.',idForExpandableSource) filter: 
'return(bobclicktest(this))' asFunction) first attributeAt: 'id');

         script: [ :s |
             lastCellIndex ifNotNil: [
                 self updateHistory.
                 s << ((s jQuery: lastCellIndex asSymbol) html: [ :h |
                     cellInfo _ (idsToCells at: lastCellIndex) third.
                     (showing at: lastCellIndex) ifTrue: [
                         toShow _ String streamContents: [ :strm |
                             cellInfo sourceArray do: [ :e |
                                     nextPutAll: e first asString;
                                     nextPutAll: '>>';
                                     nextPutAll: e second asString;
                                     nextPutAll: e third asString;
                                     cr; cr
                         h text: '[x]'; break.
                         h textArea columns: 50; rows: 20; style: 
'text-align: left'; value: toShow.
                     ] ifFalse: [
                         h text: cellInfo byteCount asString

You can see this in action at if you click 
on a cell with something in it.


jQuery: '#tableContainer'
