Clarification on RemoteAction calls (getting data into snippet from Apex class)

Hi Peter, Thank you so much for the response. Your example is an exceptionally clear example of Invocable Method! This is perfect for using Action Framework and calling Apex Method.
A couple of things if you check out Zach’s post. He isn’t using Action Framework and is able to access the method and have value returned.
I would love to use Action Framework but I need to use the returned List in a snippet. And while I know we can capture lastAction and named values. Not really sure how to get it into the next snippet AND List is not a supported return type for invokables. The object I will be getting may change as it is a third-party construct.
I will selfishly say I am looking forward to similarly awesome answers to questions to follow shortly. Thanks again!!
