/**
 * Retrieves uuid of OpenmrsObject instance from the storage based on identity value (i.e. PK).
 * <p>//from  w ww . j a  va  2 s  .c  om
 * Remarks: It is important for the implementation to avoid loading obj into session while
 * trying to determine its uuid. As a result, the implementation uses the combination of
 * reflection to determine the object's identifier value and Hibernate criteria in order to
 * build select statement for getting the uuid. The reason to avoid fetching the obj is because
 * doing it causes an error in hibernate when processing disconnected proxies. Specifically,
 * during obs edit, several properties are are disconnected as the form controller uses Criteria
 * object to construct select queury session.clear() and then session.merge(). Finally,
 * implementation suspends any state flushing to avoid any weird auto-flush events being
 * triggered while select is being executed.
 *
 * @param obj Instance of OpenmrsObject for which to retrieve uuid for.
 * @return uuid from storage if obj identity value is set, else null.
 * @see ForeignKeys
