Ah....I never would of thought of that. I was under the impression that submitting the option value from the select list would of been enough but it appears I misjudged how the life cycle works. In any case, thank you so much for pointing that out so quickly Dave.
I also had to implement prepare() on the HelloWorld action as well and paste in the same init code for the Collection as I had with the CreateTicket action. Without that implemented method and logic, I got the same error. I'm going to write a wiki page on how to do this end to end validation with these types of fields in the next few days because I found it kind of hard to do with the existing documentation. I'll post the link once I write it. Again many thanks Dave!
