I'm trying to use project facets in Eclipse but the "project facets" section under "project -> properties" is gone. I noticed this when switching to Eclipse Juno from Eclipse Indigo. I thought this was related to Juno, so I switched back to Indigo, only to find the "project facets" were gone there too. I tried both versions as a fresh install and with a clean workspace.
Searching the web for this issue only came up with "go to 'project -> properties -> project facets'", but this simply isn't possible.
UPDATE:
I managed to break it down. The facet related stuff disappears after I installed the "JBossAS Tools" package from the JBoss update site (http://download.jboss.org/jbosstools/updates/development/juno/).
Steps to reproduce:
I installed the "JBossAS Tools" package from the nightly built update site. This didn't cause problems regarding project facets.
