Is it possible to pass model data to an invocable method who’s parameter is a List of the SObject type?

For example (taken from https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_annotation_Inv…):

public class AccountInsertAction {  @InvocableMethod(label='Insert Accounts' description='Inserts the accounts specified and returns the IDs of the new accounts.')

public static List<ID> insertAccounts(List<Account> accounts) { ... }

I’ve been able to Expose an Apex Class as a parameter but cannot seem to get concrete SObject Types to work. Each time I choose the Apex action and then type anything at all in to the parameter value property, the value is not being “saved” (when I click away and click back its gone) and from that point on, changing the Apex Action property to a different action doesn’t change the parameter list. In short, the property viewer basically dies but there is no exception, no error message, etc.

Before I capture all the steps and log the issues, first question is whether or not doing this is even supported? Outside of a few community posts, I can’t find much information on calling Invocable Methods from Skuid (if this exists, can you provide link please?).

Thanks!
