Hi,
A. My best guess (and it is a guess) is that your onBeforeInit is not
firing because the listener registration is happening in the 'init'
processing, which is _after_ onBeforeInit would have fired. I'd be
intererested to know why it has to be 'before' and not 'after'. My sense
is that you should avoid 'before' unless there is some reason you can't use
'after'.
B. I strongly suggest that you look into using ND-supplied adapters and
anonymous inner classes. With this approach, you only have to define
methods that actually do something for you, and you have more flexibility,
in that you can support two or more completely different listeners even if
they share method signatures, which you can't do (at least not easily) if
the class directly implements the listeners.
Here's a suggestion based on your sample code. I'm assuming that you
really want to put in code for onBeforeInitEvent, onBeforeDisplayEvent, and
onBeforeHtmlOutputEvent, and not for onAfterInitEvent.
