Hi Rudi,
now i understand what you want.
your _getPersonTable() is recursive invoked, this must be considered
at component creation.
are you realy sure you want this?
if so you need at least the following:
a managedBean with a getter to fetch the outher list of person,
each person object has a same named getter to fetch the sublist.
following is your code a bit modifyed, something like this may work.
