Are you sure that expression "#{facilityTable.facilities}" doesn't return a collection that contains the value NULL?

Everything else looks ok to me at first glance - though forceId really really sucks, and should be avoided if at all possible as it totally breaks "encapsulation" of pages.

Could someone please help. Is this a valid structure to have a data scroller or a command link inside a tab in a tabset.

Thank you,
