I speak from personal experience.
Whoops ! I'm really sorry but I think I made a stupid mistake in my zapi.getMultiAdapter() call, because I used a "custom" request as parameter instead of the initial request I received in my JSON MethodPublisher subclass ; that's probably because of several tests I made to get things working as I need... :-( Really sorry again, but now it works perfectly...
