Genetic Algorithm

I'm evolving a 2D cellular automata. I have a PatchToroid of Cell objects (Cell is a class I defined) each cell updates it's state based on a lookup table. I'm using the GeneticAlgorithm class provided by Breve to evolve the behaviour of the cells.

However, I'm having real trouble visualizing the individual runs. The problem is that when a new individual is selected by the Genetic Algorithm, the visualization is not updated. I continue to see the previous individual running?!?! It's as though the controller is not being told to display and update the new individual. How do I force the controller to render and update the current individual?

I've attached my code, if anyone can help that would be grand!

Many thanks,
