Riyad,
You where correct, the log file contained the error “Could not set the project description for centerline-webapp because the project description file (.project) is out of sync with the file system.”. I refreshed the project and was able to add “Web Capabilities”.
After clicking through some warning messages because faces-config.xml already existed and web.xml already contained the jsf configuration, the JSF editor appears to be working. Hopefully ME v5.0 will be make it easier to use a project that already contains JSF configuration.
You may mark this as “closed”
Thank you,
Paul Spencer
