NullReferenceException, sprite collection editor now working

[kallekarkkainen]

Hi,

I've got a problem with the sprite collection editor, as it will not show any content.

It spills these:

Code: [Select]

NullReferenceException: Object reference not set to an instance of an object
UnityEngine.GUILayoutUtility.DoGetRect (UnityEngine.GUIContent content, UnityEngine.GUIStyle style, UnityEngine.GUILayoutOption[] options)

followed by

What can I do? I basically just created a sprite collection, and tried to open it's editor.

I'm on 4.1.0f4

I researched it a bit further, added some debug lines along the skin part trying to find if there was something breaking in the skin. Then it started working (after restart). I don't even... *sigh*

I've had 4 reports of this. Not an alarming number, but still slightly worrying regardless.
In half of the cases it has been because of GUID corruption due to copying/sharing stuff without meta files.

How/when did this start happening?
Did you upgrade anything?

Well, if my memory serves it went exactly like this:

• I downloaded the 4.0 unity
• I bought the tk2d, and some other stuff (not related)
• I started a project, worked on it for a few days
• Updated to 4.1
• Unity started working really strange (when starting the game, it would add red text to its controls and all that, game pausing would clear this), at this time I noted the exceptions for the first time.
• After that, restarted unity a few times, kept seeing a lot of exceptions
• Then considered updating tk2d, or canning the and starting fresh
• debugged, and magically after restart, the problem was gone

I don't think this fills the requirements for being labeled a heisenbug, as there is my project that transitioned from 4.0 to 4.1.

If you happen to figure it out, I'd really like to know.

I'll look into this. Thanks for the comprehensive report
What platform are you running on?
