Operating System
Windows 10
What did you do?
Use a python node run with IronPython 3 engine that output a list from a Windows Form Window.
``
What did you expect to see?
When running in IronPython 2 in previous version the node behaves normal, but with IronPython3 the output shown underneath the node initially show list and when I click to pin the values it shows null. However, the nodes that follow up after this one seems to get the values from the assumed list even though the final output value shown is null.
What did you see instead?
Null value in the ouput of the node
What packages or external references (if any) were used?
Attach the full code:
