Environment
NetIQ Operations Center 5.0
Situation
NOC 5.0 Dashboard currently runs on liferay 5.2.3 and you have added more then 10 communities to the system. When you login you can only see 10 communities. There is a portal ext property listed by liferay but it does not work and Liferay has a BUG which is supposedly being fixed in Liferay 6.x.
Resolution
Unfortunately, there is no way currently to get around issue. You can view more communities through Control Panel.
