Look for changes in associations of entity in recomputeSingleEntityChangeSet ?

[fGuix]

Hello,

I'm following up on those because I get a similar problematic:
#10580
#7685

I'm completing some data on an entity in my OnFlushEventListener, and among them, I update some manyToMany relationships.
It works almost completely with recomputeSingleEntityChangeSet() but the relationships are not updated.
Using only computeChangeSet() breaks the case where we are creating a new entity.

The workaround I found is the following (working both in creation/edition, and updating relationships):

// recomputation of the changeset
$unitOfWork->recomputeSingleEntityChangeSet($entityManager->getClassMetadata(XX::class), $entity);
$unitOfWork->computeChangeSet($entityManager->getClassMetadata(XX::class), $entity);

My comprehension of this is that the computeChangeSet() checks if there is changes in associations, where recomputeSingleEntityChangeSet() seems not.

My questions:

• shouldn't computeChangeSet() avoid forgetting about the creation datas ?
• shouldn't recomputeSingleEntityChangeSet() also control the associations?

Thanks in advance for your feedback.
