Re: T5: Beaneditor annotations are ignored when fetched as lazy association

[Pablo dos Reis <pa...@gmail.com>]

Hi Andreas,

I recommend to save the entities separate.

save(A); save(B); save(C); save(Main);

Maybe it has been a bug in hibernate.

Andreas, are you putting the annotations in the fields or in the getter  
methods?

I guess Pablo is right: it seems that the proxy used by Hibernate doesn't  
have the same annotations in fields, while it keeps the annotations in  
methods.
