Behavior.AssociatedObject in AttachableObject.OnDetaching is null (bug)
Hi there!
If we use AssociatedObject in custom Behavior.OnDetaching method we get NullReferenceException :(
For example:
Noesis GUI version is 3.2.2, Unity version is 2023.1.13f1.
Thanks in advance.

For example:
Code: Select all
protected override void OnDetaching()
{
base.OnDetaching();
AssociatedObject.PreviewKeyDown -= OnPreviewKeyDown; // NullReferenceException
}Thanks in advance.

Hi, this issue is already reported here: #2730.
It is happening because the associated object is being destroyed and then OnDetaching is called.
While we fix it, you can just check if the associated object is null before using it.
