WP8 UIButtonScale cause exception on OnHover

[Lotti]

latest unity (4.5.1) with latest ngui (3.6.7)

1. System.Runtime.InteropServices.SEHException: External component has trown an exception.
2. at UnityEngine.Internal.$Call.Invoke39(Int32 arg0, IntPtr method)
3. at UnityEngine.Component.InternalGetGameObject()
4. at UIButtonScale.OnHover(Boolean isOver)
5.  

I think it is (as usual) a problem unity side. Do you think there is the possibility to fix this one?

Do you have stripping turned on?

OnHover function is:

1.         void OnHover (bool isOver)
2.         {
3.                 if (enabled)
4.                 {
5.                         if (!mStarted) Start();
6.                         TweenScale.Begin(tweenTarget.gameObject, duration, isOver ? Vector3.Scale(mScale, hover) : mScale).method = UITweener.Method.EaseInOut;
7.                 }
8.         }

Since the error message mentions InternalGetGameObject, I assume it's trying to do the "tweenTarget.gameObject". Is 'tweenTarget' null?

[Lotti]

No stripping is off, but we are using .net 2.0 subset.
Target may be null or not. Depends on how much i paid attention while developing the gui. However it seems to me that uibuttonscale works fine also with null target.

[ArenMook]

It sets the target itself if it's null, as I recall. But if it's called before it's set, it can still be null. Either set it, or add a null check for that.
