Compile errors attaching ParticleSystemComponent to Actor

Ver 4.4.1. I’m trying to attach a particle system to an Actor, but am failing at the first hurdle.

.h:

	UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = Projectile)
	TSubobjectPtr<UParticleSystemComponent> PSystem;

.cpp:

#include "ParticleDefinitions.h"
.
.
.
	PSystem = PCIP.CreateDefaultSubobject<UParticleSystemComponent>(this, TEXT("Particles")); 
.
.
.

On Compile I get:

Error	1	error C2440: 'initializing' : cannot convert from 'UParticleSystemComponent *' to 'UObject *'	e:\ue4\unreal engine\4.4\engine\source\runtime\coreuobject\public\uobject\UObjectGlobals.h	569	1	ReconOne
Error	2	error C2439: 'TSubobjectPtrConstructor<UParticleSystemComponent>::Object' : member could not be initialized	e:\ue4\unreal engine\4.4\engine\source\runtime\coreuobject\public\uobject\UObjectGlobals.h	569	1	ReconOne

Now, I’ve done lots of searching on this error. Seems to be a common issue, however the solution I always see is to include ‘ParticleDefinitions.h’. I do this, but it doesn’t seem to fix it for me?

Anyone got any ideas what else it could be?

I’ve actually answered my own question. Two additional includes solves the problem:

#include "ParticleDefinitions.h"
#include "Particles/ParticleSystem.h"
#include "Particles/ParticleSystemComponent.h"
