Title: 3.4.9 ScrollView Issues
Post by: AtomicBob on February 13, 2014, 01:50:36 PM

I dynamically populate a ScrollView at one point, and I noticed 2 oddities.

1) ResetPosition doesn't work if the object is disabled in the hierarchy. This is a problem for me since when I go to a new screen, I populate the ScrollView before I enabled the screen. I can work around this, but it'd be much more convenient to be able to reset scrolling position while the object is disabled.

2) In an attempt to work around 1) I noticed several methods throw exceptions if the ScrollView has never been enabled. For example, MoveAbsolute throws an exception because mTrans is null. MoveRelative throw one because panel is null.

Yeeeah... you should not work with something that has not even been started yet. The initialization happens in Awake(), which is the first thing executed as soon as the component has a chance to start up. Awake() is executed first -- before OnEnable() (and regardless of whether the component is enabled or not). In your case I am guessing the game object is disabled outright... so I strongly advise you to first enable it before working with its components.
