[Hibernate] Components without public no-arg constructor

[Urberg, J. <ju...@ve...>]

I notice we can now map classes that don't have public no-arg constructors.
Is it possible to extend that to components also?  

Many of the components I use will be value objects and I'd like to make them
immutable (including composite ids).  I could do this if Hibernate could use
a private no arg constructor.

Thanks,
John

Ah. Interesting. If I wouldn't have just checked the code I would have
thought a private noarg constructor was allowed for components also - but
you are quite correct; ComponentType uses Class.newInstance() to instantiate
components. You wanna make a patch, John? (Probably refactor the code for
this out of the persister package and onto ReflectHelper...)

peace

Gavin
