Setting the entries in a value list?

[Joseph_Oster]

This version of @AndersDeleuran’s PVL (PopulateValueList) Python component has changes to fix a few anomalies I encountered:

1. Added code to accept only Keys. If no Values are are connected they will default to the Keys.

if not Values:
    Values = Keys

2. Added Type hint = ‘str’ (String) to all three inputs, making it possible to use integers without error.

3. Handle empty Value Lists by changing this:
   selected = obj.FirstSelectedItem.Name
   to this:
   selected = obj.FirstSelectedItem
