Title: NullReferenceException - How to track down the problem?
Post by: jess84 on April 25, 2014, 11:21:54 AM

Hi,

So I have this popping up every time I play my level - however there's a lot of things going on, so I have no idea where to track it down:

NullReferenceException: Object reference not set to an instance of an object
HutongGames.PlayMakerEditor.FsmEditor.Update ()
FsmEditorWindow.Update () (at Assets/PlayMaker/Editor/FsmEditorWindow.cs:319)
System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) (at /Users/builduser/buildslave/monoAndRuntimeClassLibs/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:222)

UnityEditor.EditorApplication.Internal_CallUpdateFunctions () (at C:/BuildAgent/work/d3d49558e4d408f4/artifacts/EditorGenerated/EditorApplication.cs:214)

I don't see any references to any of my names objects/actions in there - so I have no clue.  It could also be related to an editor add-on that I tried out but later deleted.

Any ideas how to find the offending object?

Do you get the error with the Playmaker editor closed?
Please submit a bug so we can get more system info etc. If you've already submitted a bug please add the bug number here so I can take a look...

Just tested with the PlayMaker Editor closed... and I don't get any errors.

So is this a bug, rather than an error caused by something I've not done correctly?

I've just submitted a bug report anyway.
