I'm planning on attending the
groovy code camp here in CO in a couple weeks, and have a couple groovy/grails books, which I have yet to read.
That said, assuming I can dig into them and the language over the next week or two, which aspect of Groovy/Grails would be a good thing to bring up at the class? They are taking questions and it's pretty open, so what should I plan on asking in order to leverage and instructor vs a book?
In other words, I've heard great things about Grails in Action. But there is something that you probably left out (due to length) or something that is just a little more difficult to grasp just from reading. What would that be or what should I look out for (and what can I plan on asking to a 'live' instructor in a few weeks)?
