rich:datascroller expects the entire list to be loaded in memory. Then it calls List.get multiple times.
but i want to it to load only the part that the user is actually viewing.
Is there a way to change this behavior?
please help me to solve this
so you should extend extendedDataModel (and probably implement Modifiable interface if you need to get it working also with sorting and filtering in the same way.) check both sample on richfaces-demo. Check out the current code from trunk in order to get latest samples (modifiable model sample currently not deployed it will be available online in after 3.3.1GA)
