My project was working fine before. After I added a few css files and js files from the other project, the preview as common resource or mobilesimulator produced this error. I have tried the suggested methods in this discussion thread (remove the folders in the temp dir, clean the project and reboot). But still could not fix it. Anything special in Worklight 6.2? Thanks.
