I have an extension I'm working on that uses a CEP panel. Everything was displaying fine in CC2014, then I updated to CC2015. I have gone through the manifest.xml and adjusted the version of everything. I downloaded the new .js files for CEP 6. I updated the CSXS.6.plist to enable debug mode.
The panel still isn't showing up. Is there some issue with extension panels in CC2015? Or is there something I missed updating to new version numbers?
Problem solved. OSX hadn't updated it's preferences to reflect the plist update. Solution was to killall cfprefsd to force the update. Panel is loading normally now.
