Description Gordon Yorke CLA 2011-02-16 10:04:26 EST 
valueFromPKList is used when loading Entities by PK for a relationship.  Currently this code issues a ReadObject query for each PK value and this is terribly inefficient.  The code should be changed to bulk load from the cache and then bulk load from the database using IN.
