...If you do that, summary could potentially be set by something
other than your function. Instead, what you want is to have is a
getter without a setter, like this:
[Bindable (event="summaryChanged")]
public function get summary():String {
var sumValue:String;
if (_repeat.length>0){
sumValue = 'Repeat: ' + _repeat + '\n';
}
if (_duration.length>0) {
sumValue = Duration: ' + _duration + '\n';
}
...
}
And you'd change your setters for the applicable variables to look
like this:
public function set repeat(value:String) {
if (value != _repeat) {
_repeat=value;
//this is the new code!
dispachEvent(new Event('summaryChanged');
}
}
Note that I'm assuming you're using an actual model class, not an
mx:Model. If you're using an mx.Model, go with the first advice you
got.
