Fixes #4252 Cascading refresh to lazy loaded assocations

[zluiten]

Fixes #4252
Closes #1218

Bug description

Refreshing an entity resets toMany (extra) lazy loaded associations to an empty collection before the refresh operation is cascaded to its underlying associations. Meaning objects that should be refreshed stay unrefreshed in the UoW.

Fix

The fix simply cascades the operation to its associations before refreshing the current entity.

Any news regarding this issue?

I'm facing the same problem as cascade={"refresh"} only refreshes parent entity from oneToMany relation.

I have to manually refresh the Collection as mentioned in this post.

I have the same problem, cascade={"refresh"} declaration, refresh only parent entity from oneToMany relation.

I am also facing this issue. This is probably not the best solution, but current workaround I use is:

    private function refreshCollection(Collection $collection): Collection
    {
        foreach ($collection as $item) {
            $this->entityManager->refresh($item);
        }

        return $collection;
    }
