you can create the function as bindable. If the functions values are bound
then there shouldn't be a problem. I don't think unsure I would have to
test.
very nasty you could do.
<mx:Text id="summary" text="Start Time: {model.start +
model.repeat?'\nRepeat: '+model.repeat:new String()}" />
Well I wouldn't actually use new String() I would rather use two single
quotes '' but that looks like a double quote on this monitor so I deemed it
confusing.
but if you have a model object. Why not add summary as a field to that
object?
