Desktop Flow Custom Actions - ActionSelector with nullable enum

(0) ShareShare
ReportReport
Posted on by fcobo 2

Hi there!

 

I've been developing my custom Actions with ActionBase class in c# and used the ActionSelector when I want to display an enum type as a dropdown in the UI. However, I got some scenarios where that enum value can be null and based on that, the action will behave differently. Is there any way to not to select any option from the dropdown or any other workaround?

 

Best,

    Hey,

     

    That post does not mention anything about nullable enums. What if I do not want to select an option from the enum? It seems the tool forces you to do it by passing a default value.
