Unity Version: 2020.3.22f1
By the way. It's a great library and i use it for my project deeply. hope it gets better and better
Hey, thank you for the bug report!
I've tried looking into this issue a while back and this seems to be a tradeoff when using generics to implement events via ScriptableObject. That is, if you use:
[SerializeField]
private MyCustomClass<T> myCustomClass;
Unity can't find the appropriate assets and populate the object picker list. See this forum post for more info: https://forum.unity.com/threads/generic-scriptable-object-fields.790763/
I've created a new issue https://github.com/chark/scriptable-events/issues/17 which should address this by adding a custom way of searching for these assets. This will be done after the v2.1.0 release which will have a lot of cool features!
