Rowsorting of TableView with SortedList/FilteredList

[Jonathan Giles]

Funny you should ask about this - I just blogged about SortedList and 
TableView the other day, over at FXExperience:
http://fxexperience.com/2013/08/returning-a-tableview-back-to-an-unsorted-state-in-javafx-8-0

Of course, I can see that you've already read that post (I see a comment 
from the code in my post in your code below). What might have been 
missed is that I noted earlier on in the blog post I had to make a few 
small changes to properly get SortedList support in TableView, so you'll 
want to try again in b102 (or b103).

Regarding your use of FilteredList as well - I've not tried this at all, 
but I'll add it to my todo list to investigate today. I imagine there 
might be a bug somewhere. Whatever I find will probably make for a good 
post at FXExperience, so keep an eye out there too.

Thanks, and if you do run into further issues, please don't hesitate to 
file bugs. In general, if TableView isn't sorting then something is 
going really wrong!
