Exception raised on Inspector

[William Besnard]

Hi guys,

I ran into an exception while working on a custom class:

D:/Sirenix/Sirenix Solution/Sirenix.OdinInspector.Editor/Core/Children/GroupPropertyChildren.cs:50) UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

The class creating the exception is the following:

[Serializable]
public class TagList
{


    [ValueDropdown("PotentialTags")]
    public List<String> Tags;

    private ValueDropdownList<string> PotentialTags { get { return EditorLinkedSceneManager.Instance.BuildTagsDropDown; } }

    public TagList()
    {
        Tags = new List<string> { EditorLinkedSceneManager.NoTagTag };
    }

}

where

EditorLinkedSceneManager is a singleton and BuildTagsDropDown is:

  [TabGroup("Tags"), SerializeField, PropertyOrder(1)]
    private List<string> buildTags = new List<string>();

    [TabGroup("Tags"), ValueDropdown("BuildTagsDropDown"), SerializeField, PropertyOrder(0)]
    private List<string> tagsToBuild = new List<string>();

    public ValueDropdownList<string> BuildTagsDropDown
    {
        get
        {
            ValueDropdownList<string> dropDown = new ValueDropdownList<string>();
            foreach (var key in buildTags)
            {
                dropDown.Add(key);
            }
            return dropDown;
        }
    }

The object that raises the exception uses the TagList the following way:

  [OnInspectorGUI]
    private void CheckSceneRegistered()
    {
        if (EditorSceneReference)
        {
              TagList = EditorLinkedSceneManager.Instance.GetTagListObject(EditorSceneReference);
        }
    }

    [BoxGroup("Scene"),NonSerialized,ShowInInspector,ShowIf("IsLinkedSceneDefinedEditor")]
    public TagList TagList;

Any idea why the exception is raised? It is raised only once when teh inspector shows by the way.

Thanks!

Hey, on my way out of the door, but I'll look more into it if this doesn't work. Try populating the TagList in the Repaint event.

  [OnInspectorGUI]
    private void CheckSceneRegistered()
    {
        if (EditorSceneReference && Event.current.type == Event.current.type == EventType.Repaint)
        {
              TagList = EditorLinkedSceneManager.Instance.GetTagListObject(EditorSceneReference);
        }
    }

[William Besnard]

seems to be working, thanks!

[Bjarke Elias]

Great :)
