Yes, bubbles is read-only as a property, but
can be set in the constructor of an event type that exposes it (not all Event
subclasses put the variable in their constructor but I think we’re trying
for most Flex classes to do so). Constructor of DynamicEvent is:
DynamicEvent(type:String,
bubbles:Boolean
= false, cancelable:Boolean
= false)

Dynamic Events (Flex2 Custom Events?)
I was subclassing Event, and Flex 2 told me bubbles was
read-only.
I'll try using DynamicEvent then isntead; do you have the
constructor signature handy?

Re: Dynamic Events (Flex2 Custom Events?)
I don’t think the example is going
to work since you’re trying to dispatch an anonymous object instead of an
Event. Flex 2 requires an Event to be dispatched.
There is mx.events.DynamicEvent which is a
subclass of Event that is dynamic. The constructor does take the
“bubbles” parameter so you can do with it what you will. I
don’t know if any of the events that the components dispatch are dynamic,
I think probably not.

I still can't set bubbles =
true, though... bleh....

To add arbitrary properties ...
Getting tired ;)
