CN1 crash linked to skins? - codenameone

Question

I just updated to the latest CN1 sources, but now I get the below error for a project that compiled just before. Any idea about is causing this issue?
NB. I've activated CSS for this demo example since I'm trying debug an issue I have with that. Notice the line with "Failed loading the skin file: /iPhoneX.skin". I have reloaded the CN1 settings for this project, so the iPhoneX skin should be there as far as I understood.
Sorry in advance if I did something stupid, I'm pretty nagged this evening :-)

Answer 1

If you're working from sources then the skin file for iPhoneX needs to be in the JavaSEPort/src. Normally the build script copies it but we've undergone some changes in our build process and it's possible this is no longer seamless.
