Load_current_value, custom resource and library functions


How does one load functions from a library file into the load_current_value call in a custom resource? For the action block, I know you pull in the library with:

action_class do
  include My::Helper

But the methods I’ve defined there throw an "undefined method " error when I try to use them in load_current_value.

load_current_value do
    var get_feed(parameter)

In my case, I have a REST API that I hit to get the current value, so I wrote some nicely reusable methods that will do that. In the action block, this works great:

action :create do
