replace a section of ObservableList in one operation?

[Martin Sladecek]

Hi Tomas,
unfortunately, this is not possible.
I have filed a JIRA issue https://javafx-jira.kenai.com/browse/RT-32655 
for the setAll method with range.

The subList doesn't return an ObservableList, as the sublists become 
invalid once there's some structural change on the list. That would mean 
to watch and (silently) invalidate the listeners too, which might be 
confusing.
