Owen & chris were speaking on the chat, last (my) night of virtual shelves. 2 notes on their discussion : - I agree it's strange to have virtual shelves based on items. Unless i'm mistaken, it's something Steve tonnesen wrote, and, as he disappeared, we will never know if it was a design mistake or a good idea. I still vote for "designe mistake". - about deletion of items/virtual shelves : I tried, in rel_3_0/updatedatabase, to define all SQL constraint to manage such things. So, virtual shelves entries should no more be connected to deleted items. However : nothing is done in 2.2 & it requires to have innoDB & not myIsam table structure (which updatedatabase also achieve) HTH -- Paul POULAIN et Henri Damien LAURENT Consultants indépendants en logiciels libres et bibliothéconomie (http://www.koha-fr.org) Tel : 04 91 31 45 19
