When an array of custom UObjects is defined in an actor component class, blueprint instances of the component class cannot update the array elements. Array elements only update inside the blueprint, which changes all placed instances. This prevents separate instances from having separate arrays.
No - behavior occurs in 4.13.2 and 4.14.0
(BlueprintType, EditInlineNew, DefaultToInstanced)
UPROPERTY(EditAnywhere, Instanced, Category = "MyCategory") TArray<class UMyObject*> ArrayOfMyObjects;
The element value will be unchanged and still show MyObject
Element value can be set on instances of the blueprint
