Default__Object' is of class 'Object' however property 'ComponentTags' belongs to class 'ActorComponent'

It is a class derived from UActorComponent.
Supposedly it should work. (Source)
In fact sometimes it works… but it behaves erratically.

When I instantiate it like this:

TimelineComponent = CreateDefaultSubobject( TEXT(“TimelineDesintegrate”), true);

I can see it attached to the Owner component list which is an AActor Class.

But, I think I’m going to replace it with this function and a Timer.

Value = YScale*FMath::Sin(ElapsedTime * PI);

I think that more or less I will get the same curve and no problems.

Thank you very much for your reply.
