> Ok, so "data" is a property of the "sample.thing" class, but you're trying
to add a listener on your SelectBox object, not on an object of class
"sample.thing". There's currently no relationship between the two.
I'm not quite sure what you're trying to do with this property. Who sets
it? The SelectBox won't set it unless you add code to do so.
A SelectBox does dispatch a "changeSelected" event, so you could listen for
that using your common event handler method. I suspect that's what you're
trying to do. In that case, you don't need your local "data" property at
all.
this._sb.addListener("changeSelected", this._fillBox, this);
and then act accordingly in this._fillBox.
