I want to delete child Object which has one to one relation with parent object
Ex::
I am updating Parent Object which has relation(one-to-one) with child1 and child 2 object,
So before Update I get parent Object and load its related data child1 and 2.
but now while making update request I want to delete child 1 object (which has relation with ParentObject) ,
So I just set Parent.setChild1 = null; and make update request with updated Parent object. but what I see is that object is still there. Please help me.
