Hi there, 

I am having a hard time to understand this. 

One Entity Proxy (parent) contains a list of other Entity Proxy (children). 
 I build bi-directional relationship in JPA. 

On client side, I get a list of children and then immediately enable edit 
in RF, and send it to backend to persist.

>From client, I am retrieving the children list populated correctly, but 
when I persist the exact same object to backend, I see one less child 
object (it is set to null) in the setter() in EntityProxy. The size of 
children list is still the same, but obviously one of the child is now 
null. 

Why is that the case?

Thanks,
Yan
