Yes, Tony, I expect to see you this week. I won't next. I will be out of office attending Groovy conference I organize - GR8 Conf US 2012 - http://gr8conf.us.
I do expect the issue to be something minor. I hit the roadblock late in the day and no longer had the energy to debug further. I am working on other issues in the meantime. However, if there was something obvious someone pointed out, I'd jump back into this.
Thanks! See you Wednesday!
using the visualizer as part of a unit test is something that we do for some of our tests. It looks like you're on the right path but something minor must be wrong. I believe I'm going to see you next week so lets sort this out face to face.
