I'm aware of the large gap between 3 and 5 and may require some redesign on
my part. That is why I'm using native tapestry links. In 5.0.15, the
ComponentResources class has the createActionLink deprecated in favor of
createEventLink. There are only 2 difference between ActionLink and
EventLink according to the API, the way it is controlled and the way it is
triggered.
I do want to use an EventLink in my situation, and do this through
ComponentResources.createEventLink(). The tutorials show you how to use the
ActionLink in a template, whereas in my case, the component is created via
Java code. Perhaps I do not understand what the "context" argument in the
createEventLink() method is used for. I believe that the first argument
would be the name of the method to invoke? How do you identify the handler
of the event when creating the EventLink? Tutorials show this binding done
through the @OnEvent annotation and specifying the event name via the
"component" attribute in the annotation or the "id" attribute of the
element.
How would I bind these properties using a pure Java implementation? My
previous T3 components never had a template file, and rendered purly in
Java.
Thanks
