This is what Symfony's profiler outputs when I dump the result of ->getPictures():
PersistentCollection {#292 ▼
-snapshot: []
-owner: User {#270 ▶}
-association: array:16 [ …16]
-em: EntityManager {#53 …11}
-backRefFieldName: "user"
-typeClass: ClassMetadata {#272 …}
-isDirty: false
#collection: ArrayCollection {#293 ▶}
#initialized: false
}
Somehow the collection is not initialized and it has no items, although there are some in the database... What point am I missing here?
