[rules-users] Sudoku example in Guvnor 5.0.0 CR1

Hello, I was wondering if anyone has tried using Guvnor with the Sudoku example in examples for 5.0.0 CR1. We are looking at Guvnor's functionality and I'm have difficulty running any successful scenario's against the Sudoku rules in Guvnor. I know this is one of the more complex examples in the drl package but it seems that there would have to be a lot of work done to get any benefit from Guvnor without rewriting some of the Java Classes. Anyone willing to share any experiences with this? Thanks, Jon
