[EP-tech] Re: Browse pages

Thanks all for the help on this. I think it’s started to get in there!
I’ve managed to make the changes I needed to the screen, but I’m still
struggling with the view. I get what needs to be done, however when I
change up the requisite view function in views.pl I get nothing.

For some reason the output of our creators is not in alphabetical order.
The function in views.pl is:

{
		id => "creators",
		allow_null => 0,
		hideempty => 1,
		menus => [
			{
				fields => [ "creators_browse_id" ],
				new_column_at => [1, 1],
				mode => "sections",
				open_first_section => 1,
				group_range_function => "EPrints::Update::Views::cluster_ranges_30",
				grouping_function => "EPrints::Update::Views::group_by_a_to_z",
			},
		],
		order => "-date/title",
		variations => [
			"type",
			"DEFAULT",
		],
        },


And you can see an output from that here:
http://eprints.lincoln.ac.uk/view/creators/index.M.html

I have looked here: http://wiki.eprints.org/w/Views.pl and implemented
some of the different parameters into the function, but the view does not
change. I’m restarting the server and setting “Regenerate views” in admin
(all done on a local copy which is a replica of the live copy)

I’m wondering if I’m missing something?
