Ah, I think the problem is that I overrode the setup() method from AbstractGenerator, but didn't look at what it was doing in the original - I presumed incorrectly that it did nothing. You should be able to get at the source by adding super.setup() to the first line of the new setup() call below. Now that I've looked more carefully, we could get rid of our own implementation of setup and use the instance variable objectModel from the superclass to get our parameters from within generate if we really wanted to - on the other hand, for demonstration purposes it's better in my view to show that it's available as a callback method from the container for performing setup tasks.
Thank you by the way for reorganizing the output to be more xml friendly. I've already started work turning this example into a how-to for the documentation. Would you mind if I incorporate your modifications for that so I don't have to come up with another example?
