My simple example is assigning regions:
If I have a BO for States and a BO for Regions and I want to assign states to a Region then the user will only see 20 available selections. There is no way for them to filter the states to get exactly what they need because the states for each region can be completey different (BTW this is just an example).
If I select 3 states on the first page and don't commit them then when I page over and select states on the second page I will only get the states on that page committed.
Maybe this is not the way it is supposed to work? I never heard anything on this from anyone so I am assuming that this is the way the system is designed to function.
I am always open to suggestions that will make me better at using this system.
