I have started again all the tutorial from the begining, trying to not miss any configuration setting even the ones displayed on pictures, finding that the tutorial example now works. I think the first time i have tryed it i missed to activate the anotations facet in project properties because this configuration step is not explained in the tutorial unless you take a close look into the tutorial images. Probably that was the cause of the mentioned error, not so sure, but the tutorial example really works.
