The visual component of the Visual Page Editor, which depends on XULRunner, does not operate in the 64-bit version of JBoss Developer Studio on OS X and Microsoft Windows operating systems. To work around this restriction, you must install a 32-bit version of JBoss Developer Studio on 64-bit OS X and Microsoft Windows operating systems.
Is this still correct or does it need updating? I think there was talk of trying to do away with XULRunner but I couldn't find a JIRA
Thanks,
