      * Returns a list of references that must be refreshed after a lookup performed on an attribute is performed.

      * A lookup on an attribute may cause many attribute values to be updated upon return from lookup.  Generally,

      * the returned attributes are the PK of the BO being looked up.  For example,

      * a lookup on an account number attribute will cause the chart of accounts code and account code to be returned.

      * 

      * These returned attributes may cause other references on the page to be returned.  For example, an account number lookup

      * may cause the chart code to change, and if there is also an ObjectCode reference in the BO, then any change in the chart code will cause the

      * referenced ObjectCode BO to be changed.

      *

      *  

      * @return a list of reference names that could be affected by lookup return values
