@Richard: thanx for your answer. As for the performance penalty: is the
bubbling process taken care of by qooxdoo or by the browser?
@Dietrich: according to the documentation dataEvents are non-bubbling:
"fireDataEvent() Creates and dispatches an non-bubbling data event on
this object."
The event set for class properties are of this type.
Regards,
Martijn.

Onderwerp:Re: [qooxdoo-devel] When to use fireNonBubblingEvent?
What kind of event is fired if I have a property bound event like this:
value :
{
check : "String",
event : "changeValue",
init : null,
nullable : true
}
Bubbling or non-bubbling?
The event is automatically fired by some (more or less) hidden logic
within qooxdoo.
I have some huge forms with a lot dependencies between the form fields
which are triggered via the changeValue and changeModel events.
This may be something to look into because of possible performance gains
especially on IE8.
Regards
Dietrich
