From dc9a52c9e0e63758fcf224fbe1171e24c17e8f44 Mon Sep 17 00:00:00 2001
From: Denis Flaven <denis.flaven@combodo.com>
Date: Thu, 18 Nov 2010 16:41:09 +0000
Subject: [PATCH] Improved implementation of the 'autocomplete' input and fix
 of quite a few related issue with aysnchronous inputs. Autocompletes are now
 restricted to external keys only. Some details: - Autocomplete now matches on
 'contains' instead of 'begins with' - The minimum size of this match is
 configurable in the config file and per attribute ('min_autocomplete_chars').
 - The maximum size that turns a drop-down list into an autocomplete is
 configurable in the config-file and per attribute ('max_combo_length'). -
 Better feedback when expanding/collapsing search results lists. - 'Pointer'
 cursor on the link to Expand/Collapse results lists. - The 'mandatory' state
 of an attribute is no longer lost when some part of a form is reloaded
 asynchronously
