Kevin Van de Velde updated DS-749:
----------------------------------
Attachment: Bitstream order UI patch v0.3.zip
Uploaded the latest patch (v0.3) which with not hide the buttons but disable
them. This was done because if the buttons where hidden in themes that didn't
have alternating row colors (e.g. Mirage) it would be confusing.
> allow for bitstream display order to be changed

> This patch allows user with access priviledges to edit an item to change the
> order in which a bitstream is displayed
> in the item display. This patch is for the JSPUI.
> The first thing that needs to be done is that a new field needs to be added
> to the bitstream table with the following SQL:
> alter table bitstream add display_order integer;
> Then that field needs to be populated with the values in the sequence_id
> table. I have provided a perl script
> that I used to do this: fix-display-order.
> Once this is done, make the following code changes.
