Hi Ben,
Thanks for using Pivot. Yes, the Renderer interface is just for displaying
(rendering) the data. If you want to change values then you need to implement
(also) a ListView.ItemEditor (basically you can subclass ListViewItemEditor)
and populate it with the same two fields as your render
So I've followed the list tutorial on the website:
http://pivot.apache.org/tutorials/lists.html
I've decided to make my own list, using a custom list item (it just has two
fields, a title and a name) and so a corresponding custom renderer to
display the title as a label and the name in a textinput
