Hi,
Anything is possible, you can even use bindings if you want but (I
think) you will need to set it up in code.
Never tried doing this before so if anyone else knows how to do it in
IB I'd be interested.
Observe the first array controller, when the selection changes create
a new array holding your limited number of items, posting KVO
notifications for your changes.
Your third array controller then observes your limited selection array.

Hi there,
I have a problem here and I am not sure I can handle it easily.
I have to array controllers, one's content set is bound to the
selection of the other. this is all working fine, i have it all set
up to show the bound data in a table view, which is fine too.
now what i need to accomplish is to have a third array controller
that is bound to the selection of the first one as well, but only
displays the first 15 entries of the given selection. so say the
selection in arraycontroller 1 has 35 entries, i only want this new
arraycontroller3 to handle the first 15 elements, while i want
arraycontroller2 to handle all 35. is this possible? how should i
try to do it?
any thoughts are appreciated.
Ben
