OnMouseUpAsButton never gets called

Hi, i have a script for a 3D gui system and I am having issues with having OnMouseUpAsButton( http://unity3d.com/support/documentation/ScriptReference/MonoBehaviour.OnMouseUpAsButton.html )

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class highscore : MonoBehaviour {
6.     public AudioClip button;
7.     public GameObject text;
8.  
9.     void OnMouseEnter()
10.     {
11.         audio.PlayOneShot(button);
12.         text.renderer.material.color = Color.red;
13.     }
14.  
15.     void OnMouseExit()
16.     {
17.         text.renderer.material.color = Color.white;
18.     }
19.  
20.     void OnMouseUpAsButton()
21.     {
22.         print("OnMouseUpAsButton");
23.     }
24.  
25.     void OnMouseUp()
26.     {
27.         print("OnMouseUp");
28.     }
29. }
30.  

That is my my code.Everything but the OnMouseUpAsButton works.
This refuses to work in javascript as well. Has anyone else encountered this issue?

 

It only works in Unity 3.4.

oh... I should have tried that.. lol duh. thanks

 

Just FYI, the "History" link that's on all pages in the docs provides a list of which functions and so on were added to which version of Unity.
