Hmm, it's possible you misread some of my code :) I realised afterwards
that I should have renamed some of the objects to something less
ambiguous than 'event' (which is just the name, as in 'sports event')
when dealing with 'events' (as in the Laszlo thingies).
The problem is more that I can't seem to say:
<attribute name="onselected" value="null" />
in a class, and thing when I instantiate that class from somewhere else,
...it refuses to see 'parent' at all.

I thought about that, but it doesn't suit my situation. I'm not
signifying data changing, I'm signifying some user feedback occurring.
In the same way as a button shouldn't need a 'click' data field in order
to have an 'onclick' event.
All that said, I might look into doing it this way, hopefully with
