OnValidate: unassigned components

In the HandleEventWithAudioExample values aren't assigned to anything.

void OnValidate () {
    if (skeletonAnimation == null) GetComponent<SkeletonAnimation>();
    if (audioSource == null) GetComponent<AudioSource>();
}

It should be:

void OnValidate() {
    if (skeletonAnimation == null) skeletonAnimation = GetComponent<SkeletonAnimation>();
    if (audioSource == null) audioSource = GetComponent<AudioSource>();
}

I've made this mistake many times before.
