List Variable

Hi ! I want to set a list of my workflow using the REST API in c#. So, I made this part of code :

Hi there,

I'm still relatively new to Bonita level coding and am trying to use the code example here to populate a LIST variable from Groovy Script but with no success...it's using code I don't know...

I don't know how to use UUID query runtime etc. and keep getting an error.

So as a full code example...can you show me how it's done...
