                 Key: TAP5-1199
                 URL: https://issues.apache.org/jira/browse/TAP5-1199
             Project: Tapestry 5
          Issue Type: Improvement
          Components: tapestry-core
    Affects Versions: 5.2.0
            Reporter: Howard M. Lewis Ship
            Priority: Minor


There's a bunch of steps in making this happen; it would be nice if it was just something like:

transformation.addEventHandler("activate", 0, new ComponentEventHandler(Event event) { ... });

The number is the minimum number of parameters. 

The semantics of this is that the handler is invoked first, with an invocation.proceed() at the end. The handler is not invoked if the event is aborted. The result of the invocation is overridden to true if the handler is invoked.
