Hi Rony, I am the developer of HiveMind, it is a web app platform that relies entirely on scripting engines via JSR-223.
You can access a demo instance: http://demo.crudzilla.com:7000/ Login with: developer/developer I have created a test file in: /com/crudzilla/cloudTest/web/rony-groovy.ste Put your code (the original one you pasted) in there and save, I'll take a look to see what might be missing.
