dispatchComponentEvent is one of the methods of the Component [0] interface.
Every page / component / mixin implements this interface through some class
transformation by Tapestry. Same as with setupRender; if you don’t implement
this method, Tapestry will do it for you.

ComponentResourcesCommon.createEventLink(String, Object...) for the
selectR
