I've found the problem. Enabling the 'debug' logging level, I saw that my services are returning subclasses of SoggettoVO.. my local VOs are correctly extending themself, so it is fine to consider all those objects as instances of SoggettoVO class, but those other subclasses are never referenced in my code.. then, yes, it was the linker optimization issue :)
It would be really a great improvement if the flex compiler was so smart to keep the classes marked with the [RemoteClass] metadata in the SWF, even if not referenced in the code.. any hope to see this in the final build of FlexBuilder 3? (maybe it's already like this - I'm still using the SDK version 2.0.1 to use LCDS 2.5) Again, I want to thank Johnny and Den for their help. Cosma
