I assume that the variable "data_name" holds data which is connected to each
checkbox group.
You can use the following snippet to achieve this
--snip--
mycheckboxgroup.setUserData("data_name", "your_data");
mycheckboxgroup.addListener("changeSelection", myDataSet.updateFunction,
myDataSet);
...
updateFunction : function(e)
{
var checkbox = e.getTarget();
var data_name = checkbox.getUserData("data_name");
value = checkbox.getSelected().getValue();
this.setData(data_name,value);
}
--snip--
This way you can use a single update method.
I hope, I understood your problem right :)
cheers,
Alex
