This example module shows in action what I've written here about paginating, sorting and filtering of a data returned by a Data Action in a Reactive App. It's self-contained, as the module both exposes and consumes the REST service used.

Currently, the REST service consumed points to my PE (kilianhekhuis.outsystemscloud.com). As long as it's up, the REST service should work, but for extra responsiveness you can change the URL to that of the environment you've published the module on.
