Which component does the "_id10:display_0:_id22" string refer to?
Might help to put in some id attributes for the data tables and
selectOneMenu.
Also, what does ManageInterviewersBean.supervisors.selectList look
like? What kinds of objects are in the list? It sounds like your
"nearly identical" list returns Integers (which there's a default JSF
converter for), but your list here returns Supervisors, for which
there will be no default converter.
