Thank you for your time everybody! For posterity: First to clarify, my very specific question is how to iterate an iterable in the model-building logic (what us old timers might call a "backing bean"). I do already know that I can use HTL to iterate the children, and I do recognize that in this contrived example it's a better separation of view/model concerns to do so. However I'm going to need to do lots of iterating on resources in my "backing beans" as I build model data for increasingly complex objects. Imagine a component that searches various parts of the JCR and filters on specific properties to generate a heterogenous list of content links... To suggest HTL just skirts around my development need in model-building logic.
Vlad's syntax solved my problem. I'd love to understand why. It seems the Iterable contains a Map or List objects with a key and resource... Is that due to Rhino? The Sling docs say getChildren returns Iterable<Resource>. I didn't expect this. I'm already feeling the pain of debugging JS Use API, which Stefan has warned about, and so did the sling docs on. I'm concluding that the JS Use API probably isn't ready and requires too much esoteric/idiomatic knowledge to give the sort of development speed one would expect with JS. I'm going to keep it as an option for very simple components. -- View this message in context: http://apache-sling.73963.n3.nabble.com/JS-Use-API-usability-or-limitations-tp4069490p4069521.html Sent from the Sling - Users mailing list archive at Nabble.com.
