That probably does work, but updates the entire item renderer, which may
result in performance issues. If the CheckBox is only a small portion of
the item renderer, there may be an optimization.
If you actually used code like: selected=“{data.makeCheckBoxeSeleted}”,
that should have generated a warning at compile time because ‘data’ is
just an object and there is no way to compute the change events for the
makeCheckBoxeSelected property. At runtime, it might have guessed at the
wrong events. Usually you have to coerce the type in the binding
expression as in:
selected=“{MyData(data).makeCheckBoxeSeleted}”
