As the comment in the next line says, we should check for an unchanged value,
i.e. userValue == activeValue

Oops. Done.

nit:

... indicates that the recommended value is in use.

Moved to one (hopefully more clear) above the if block.

[pneubeck (no reviews), 2014/08/06 17:37:35]

can be set independent of activeValue.
just move it out of the inner if block, i.e.

if (propData['UserEditable']) {
  if (userValue != activeValue) {
     ...controlledBy = ...
  }
  event.value.recommendedValue = userValue;
}

ditto, wrong negation.
