 Post subject: Merging null values

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.
http://stackoverflow.com/questions/7473 ... ull-values)

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.
