Lets say I have a parent and a child object. When I remove the child from the parent in the same activity it works. However when I pass the serialized parent into a new activity and try to remove the child it does not work.
How can I remove the child from the parent after passing it between activities?
Hi Frank,
What does the parent object in the new activity look like after you remove the child? Can you take a “snapshot” of the entire object hierarchy (perhaps in the debugger) and share it with us?

Hi Mark,
As attached the snapshot of the parent. I’ve created a demo project which can be found at:
https://github.com/fathomson/backendless_parent_child
When I save the childless parent it responds with a childless parent. However in the backendless console the parent still has a child as is when i do a findbyid.

Hi Frank,
I see what’s going… once the object is serialized/deserialized, it looses the __meta property which is crucial for determining (by the server) what has changed in the object. Sony add a public field String __meta to the parent class and it should fix it.

Hi Mark,
That worked, thanks for the quick response!
Was that something I could have found in the documentation somewhere?
Kind regards,
Frank
Hi Frank,
No, it is one of the edge use-cases which is not covered in the docs.
