[EP-tech] Re: Browse by Author shows empty

Hi Kostas

	I've had a dig through the code, and it looks like the point of group_by_a_to_z (the grouping function you're using) is to explicitly include all characters A-Z if they don't exist in the data.  I would suggest you try using the group_by_first_character function instead, which doesn't have this behaviour.  The line to change is:

	grouping_function => "EPrints::Update::Views::group_by_a_to_z",

	...to...

	grouping_function => "EPrints::Update::Views::group_by_first_character",

	However, you may find that your range navigation looks a bit funny with letters missing from the alphabet.
