Question Query can't find descendants

Hello!

I want to be able to find all ports on my node and ports with a matching direction to my other port to a list. However, it appears to me that the query is unable to find any ports that are somewhere in the visual tree on my node.

Code (CSharp):

1.  
2.         public static int GetPortIndex<T>(this EditorDNode<T> node, Port port) where T : DNode
3.         {
4.             List<Port> matches = new List<Port>();
5.             node.Query<Port>().ToList().ForEach(p => {
6.                 if (p.direction == port.direction) matches.Add(p);
7.             });
8.             return matches.Count == 0 ? -1 : matches.IndexOf(port);
9.         }
10.  

Debug.Log(node.Query<Port>().ToList().Count)

prints 0.

Any idea why this is not working?

Kind regards,
Dave

 

Where are you calling this from? I found that querying too early sometimes leads to no matches. I guess the tree must initialize before we can properly query it.
