I’m running build 1640. I’ll go through the install steps again just to make sure I’ve not messed something up. If I didn’t I’ll open the issue. No news is good news (i.e. I messed something up somewhere along the way).
I meant to include a link. Running Actions from JSON Rules was where I stopped with the documentation but I think I have enough to get someone started. The helper libraries do most of the work for you though and you just need to pull the Action from a list of discovered Actions. There is a little bit showing how to do it using Lewie’s JS library which has since been merged with the Helper Libraries and may have changed a bit.
