Thanks for your respone. Explain what you mean by, "underlying value" ?
I am setting the checkbox to be checked or not by doing:
if(item[getDataLabel()] == "Y") { cb.selected = true } else {
cb.selected = false };
>> Perhaps you need to call the superclass version of

Already being done as this is an inherited function. I am getting the
label of the current cell and using that to select the checkbox. But
this probably shouldn't be done inside this function as the setValue
function is called every time the datagrid cell is interacted with. Not
sure how this is normally done, and how to do this better, this is my
first experience with the CellRenderer API. Thanks for any advice.
