Why cascade merge didn’t work

Problem
I ran into a problem with JPA not saving my related entities when I merged them, even though I had set cascade to persist.
Solution
It turns out that both Cascade.PERSIST and Cascade.MERGE have to be specified on a JPA entity. Just PERSIST does not apply to situations were an existing entity is merged after having been linked to new entities.
