Hello,
I managed to solve it. The problem was the line at the listener:
this.setSelectedLocationId(null);
that was setting the selectedLocation to null. Why I asked before was
because I was facing a behaviour without any produced messages, so I didn't
know where to begin. In the beginning of the listener I had a
System.out.println("SelectedCountryId: " + getSelectedCountryId());
that wasn't printing anything (not even a null exception).
I found the solution ad hoc after all but anyway, thanks for the quick reply
