             Summary: Add PropertyChangingEvent and CollectionChangingEvent so that developers can handle before change happens.
                 Key: FLEX-34202
                 URL: https://issues.apache.org/jira/browse/FLEX-34202
             Project: Apache Flex
          Issue Type: Wish
          Components: Collections
            Reporter: Gary Yang


The existing PropertyChangeEvent and CollectionEvent are working great, but they only dispatches after changed, it will be great if there can be events that let developers handle before change.

Thanks.
