I got this to work great for a Spark patch but can’t seem to get it to work for mx, specifically ListBase. I tried using the same methodology of breaking it out of the SDK into an RSL but it didn’t grab. Perhaps that class is included in frameworks.swc or something. Let me know if you can suss out a way to patch an mx class, thanks!

There’s a somewhat bitter taste to this subject knowing that developers have been crying out about Adobe’s overuse of the private namespace for many years, and that if they’d changed that practice with Spark the framework would simply be extensible instead of requiring backflips to hack and patch, but at any rate I’m glad there’s someone on their team pulling for the rest of us now!

Thanks also for pushing out the upcoming Spark components in Hero early — I’ve just recently built my own global thumbnail caching and prioritized load-queuing for the nth time and am thrilled to see it added to the framework. I’m guessing you had a personal role in getting those early-released and wanted you to know that those efforts are very much appreciated! :-)
