PM84460: LOADING EMPTY DATA INTO JSONSTORE COLLECTION RESULTS IN FAILURE CALLBACK

APAR status

• Closed as program error.

Error description

• When an adapter, which is linked to a JSONStore collection,
  connects to a backend service that returns empty data ([]) for
  the key the user provided in the load object given to
  initCollection, the failure callback is invoked even though the
  data (the empty set) was successfully loaded.  A similar
  invocation to the failure callback is incorrectly made when the
  user creates a collection with initCollection(), links it to an
  adapter, calls the collection.load() method and the adapter
  returns empty data ([]).
  

Local fix

• There is currently no work around for this issue.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * Developers using the JSONStore and initCollection with       *
  * {load: true} or calling load(), where the linked adapter may *
  * return empty data ([]).                                      *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * If the adapter returns empty data, then the JSONStore code   *
  * will erroneously invoke the failure callback.                *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  

Problem conclusion

• The code was modified to correctly deal with the adapter
  returning an empty set.
  
  The fix for this APAR is currently targeted for inclusion in
  refresh pack 5.0.6.0.
