NullReferenceException thrown even when variable is assigned

Here are the relevant code snippets:

Code (csharp):

1.  
2.     private Renderer meshRenderer;
3.  
4.     private void Awake()
5.     {
6.         this.meshRenderer = this.gameObject.GetComponent<Renderer>();
7.     }
8.  
9.     private void Update()
10.     {
11.         this.meshRenderer.enabled = /* Check some condition */
12.     }

Stepping through the code in debug mode, I can see that this.meshRenderer is assigned in the Awake() method.

However, when the Update() method is called, a NullReferenceException error is thrown, claiming that this.meshRenderer is null.

The only explanation I can think of for this behaviour is that this.meshRenderer is nullified somehow after the Awake() method is called, but I don't know why or how.

None of my MonoBehaviour scripts implements the Start() method.

Any advice?

 

Never Mind, sorry
