Hi John, it seems you were right at the end.... I was not submitting the form. But this is not all. The original method was: MACheckboxColumn >> renderCellFormContent: anObject on: html html checkbox value: (self isSelected: anObject); callback: [ :value | self selectRow: anObject value: value ] The only way I found to make it work is like this (notice the form, the label and the submitOnClick) renderCellFormContent: anObject on: html html form: [ html label: [ html checkbox submitOnClick; value: (self isSelected: anObject); callback: [ :value | self selectRow: anObject value: value ]]] but #submitOnClick is deprecated. So I don't know how this is supposed to be fixed without such a deprecation: WAFormInputTag >> submitOnClick self greaseDeprecatedApi: 'WAFormInputTag>>#submitOnClick' details: 'Use a dedicated Javascript library.'. self onClick: 'submit()' I have my own subclass of MACheckedColumn so I override this method. But I wanted to fix it and commit for others.
