            Description

            Currently (3.2), when the bridge applies DOM updates it then scans all components looking for components with 'onElementUpdate' callbacks defined that are affected by the updated DOM region. This process occurs in JavaScript on the browser, and can be very expensive/slow particularly on IE7/8 browsers. This performance issue is preventing wide-scale adoption of the the onElementUpdate callback to improve JS memory cleanup in the ACE components.

            An improved implementation may be to compile a list of the components affected by a particular DOM update on the server, such that the bridge could then simply call each one's onElementUpdate callback in sequence and avoid the expensive searching through the component list on the browser. Presumably the callback list would be sent to the bridge as part of each DOM update message.
