Is X an EntityProxy or a ValueProxy? If it's a ValueProxy, then this is the expected behavior; you'll have to either:
- allow 'null' in your setter (you could treat it as a Boolean.FALSE if you like) - set the property value to Boolean.FALSE on the client-side - change your property type from 'Boolean' to 'boolean': there's little to no reason to use 'Boolean' if you disallow 'null', just use 'boolean' instead.
