Do you want to be able to revert child's changes without affecting the parent and other biz objects?

If yes, you woud need to set your child's biz object to be the primary when you activate the page and reset it back in deactivate. You may also temporarily disable relations (remove references to the parent). Something along these lines should work, I hope you would be able to figure out the exact implementation details.
