Hi Massimiliano,
it's better to use MonitoringFeatures.ENABLED constant instead of
"enabled" directly. Please replace it in all sources.

For the problem you've signaled...I resolved on the fly (revision
200)...it was a bug.

Now should works ;-)

However...Good work Massimiliano! I hope to include the Monitoring Aspect
in the next DEMO and, surely, in a next TUTORIAL ;-)

Mhmhm... Rather...Do you want to write it yourself? :-D

bye,
Luca Garulli
