I am not sure if you are talking the Collections api list, but if you
are
then the Glazedlists stuff provides an implementation of the Collections api
list
But then you need to pre filter the list. Because what would size() return??But going with something out of the repeater package would be better.But then still you need to filter up front because all those Repeaters do want to know the total size?
And filtering on demand doesn't work then.johanOn
Just out of my head. Paging which is based on windows size and list
size would need to take these into consideration. Not sure this change
is trivial.

the filtering should be performed in the model - it is the perfect place for it.-IgorOn 7/17/06, Juergen Donnerstag

Yeah, there's no problem implementing this in the model, other than the fact that there will be a list copy.

Yes, a List implement that filters on the fly would avoid the copy, but probably incur greater performance hits than a single List copy (due to the Linked List nature of the filtering). The current ListView implementation only works on lists.. rightfully so because you can extract the active
another key reason for list is that the index of the list is used as a primary key to identify the right item on callbacks.-IgorOn 7/17/06, Aaron Hiniker
