ManagedProperty value check

[aloubyansky]

I am getting an exception below trying to set null as a value for int. Is there a way to check the validity of the value before setting it? There is 'String ManagedProperty.checkValidValue(Serializable)' but the implementation always returns null, meaning always valid.

Should a meta type have a property like nullable or primitive? And
should there be a default value for a managed property of a primitive type?

[starksm64]

MetaType.isSimple essentially is whether or not its a primitive. SimpleMetaType/SimpleValue should be dealing with autoboxing of primatives to avoid leaking having dealing with primitives vs simple types in the admin clients.
