> I have a parent entity with a @OneToMany collection, with CascadeType.ALL and CascadeType.DELETE_ORPHAN. If I follow the following steps Hibernate throws a TransientObjectException:
> 1. Load the parent entity with its collection from database
> 2. Add a child entity to the collection
> 3. Add a second child entity to the collection
> 4. Remove the second child entity from the collection
> 5. Flush / commit the transaction
> The bug cannot be reproduced if:
> 1. The parent entity is created in the same transaction where the rest of operations are made
> 2. All the added children are removed
> The following is irrelevant for reproducing the bug:
> 1. The relationship may be unidirectional or bidirectional
> I've attached a maven project with a test case with a trimmed down version of our production code showing the bug.
