Question Field not visible in Editor for custom class

Hi!

Unity: 2019.4.20f1
XR Interaction Toolkit: 1.0.0 pre2

Unity isn't showing me in the Inspector any custom field (in this case a list, but any type really) that I'm adding to this class, that I extended from XRGrabInteractable.
See example below:

Code (CSharp):

1.  
2. public class MyXRGrabInteractable : XRGrabInteractable
3. {
4.     public List<XRSimpleInteractable> myList = new List<XRSimpleInteractable>();
5. ...
6.  

I already restarted and tested without using an XRSimpleInteractable within a Monobehaviour class and the Inspector works just fine.

Any idea why this is happening?

 

Thanks for your reply
