Table case-insensitive sorting

I want to sort a table of data on a column, but I do not want the sort to be case sensitive (ie a = A). I found a topic in the UI forum that seems to address this, but it seems to be a couple of years old and I can not find the method that they reference to overide the ItemSorter (setItemSorter). How would I do this in Vaadin 7?

Hi,

it seems that the method is in the container implementation, e.g. IndexedContainer (and probably other sortable containers too), so you should set it there. I imagine the process should be the same otherwise.

Thank you.
