5.4 Limitations with multiple child EditingContexts
You may wonder how child EditingContexts behave when changes in any
one of them is saved to its parent. The answer, for now, is quite simple:
the other children won't notice anything. This leads to some
problems, depending on the changes affected in the child EditingContext:
- if the children only update the data without inserting or deleting
any object, you can declare several children for a given EditingContext. However, any
changes committed by a child for an object
obj will be overriden when an other child subsequently saves its own changes if, and
only if, the same object obj has also been updated in that other
child.
- however, the possibility that multiple children would also
concurrently insert or delete objects
is not supported. We strongly advise against having
more than one child for a given EditingContext if you insert or delete objects in
the child, as this would lead to unpredictible behaviour.
