Yes, my original snippet doesn't work because mapping works only when there is sorting enabled. So it should be like this:

```
filterCallback: function(source_row, value) {
                    var idx = mapRowFromSource(source_row);
                    var data = get(idx < 0 ? source_row : idx);
                    return !data["VirtualStream"];
                }
```

Also can you please rename NonVirtualStreamFilterModel to just SortFilterModel (or maybe PaSortFilterModel so it doesn't have the same name as PlasmaCore.SortFilterModel)? I plan to use the sorting/filtering also with other properties, not just virtualstream and don't want to create new model for every property.
