Maybe I'm being REALLY obtuse…..but:
My use case is to make a remote call (in this case to a Confluence REST endpoint) when a folder is created in a particular site. I'm running into the same exact issue as OP, and reading this thread, it seems I'll need to develop a web script. I am able to locate the tutorials for developing a java-backed web script. However, it seems that once complete with my custom web script, I'll still run into the same problem : there's STILL no way to call a URL from the javascript called by the Rule on the folder, whether it's an Alfresco REST/Web Script URL or something else….since remote is still undefined.
As this will be a 'sometimes on' usage, my users need to be able to manage it from the Rules interface, rather than removing/re-adding a web script every time.
What am I missing?
