Hi,

I was wondering if there's a way with the JPA API to specify a strategy for merging entities ?
For example could we say to the EntityManager to merge only non null values (cf.

thanks

The merge operation copies all properties from the detached enitty onto the managed entity instance. If you want more control, you need either a manual approach or an automated reflection-based utility.

Thanks !
