New Revision: 18786

Modified:
   branches/rel_2_0/Open-ILS/web/js/dojo/openils/PermaCrud/Store.js
Log:
fetchItemByIdentity now returns null immediately upon null identity

Besides being trivially more efficient, this avoids a situation
where pcrud can sometimes time out when attempting to retrieve
a row by a null PK value.
