3.0.7f3 Upgrade, now TweenAlpha broken

[ricky]

Is there a temporary fix for this issue?  I am having a problem with this update.  The errors with uirect and tweenalpha.  I'm not having problems with any other tweens.

I tried the thread http://www.tasharen.com/forum/index.php?topic=7210.0 but that did not help me, i am not adding a child or anything.  I'm simply doing what I did before, make the gameobject active, then get reference to the component, but for some reason, getcomponent does not work with this update with tweenalpha.  I have not changed any code and this coe has worked for a good 4 months now in the same project.

***Error***
NullReferenceException: Object reference not set to an instance of an object

        msg.GetComponent<TweenPosition>().ResetToBeginning();
        msg.GetComponent<TweenPosition>().enabled = true;
        msg.GetComponent<TweenAlpha>().ResetToBeginning();
        msg.GetComponent<TweenAlpha>().enabled = true;
        float timeToDisplay = SetMessageStyle(messageStyle, msg);
        msg.GetComponentInChildren<UILabel>().text = message;

You need to attach TweenAlpha to a widget or a panel. In your example you do msg.GetComponentInChildren<UILabel> -- I'm guessing your widget (label) is on a child object. This is the object you need to TweenAlpha.

Thanks!

I put the tween alpha on the children and removed it from the parent and it works fine now:

TweenAlpha[] tas = msg.GetComponentsInChildren<TweenAlpha>();
        foreach (TweenAlpha ta in tas)
        {
            ta.ResetToBeginning();
            ta.enabled = true;
        }
