BTW, digging into code and API docs, I read:
boolean
org.apache.tapestry5.runtime.Component.dispatchComponentEvent(ComponentEvent
event)
Invoked to handle a component event. Methods with the OnEvent annotation
(or the matching naming convention) will be invoked until one returns a
non-null value.
So I updated to code above to return a JSON object instead of null. But
still throwing the same error.
