PM97582: POSSIBLE DUPLICATE PUSH NOTIFICATIONS IN SPECIFIC SCENARIOS

Download for IBM Worklight V5.0.6 Fix Pack 2 and IBM Mobile Foundation V5.0.6 Fix Pack 2

APAR status

• Closed as program error.

Error description

• Duplicate push notifications may occur in the case that the
  end-user installs the application, subscribes to push
  notifications, uninstalls the applications and then reinstalls
  it and subscribes to push notifications again.  This will only
  occur if the subscribed event source declares a callback for the
  onDeviceSubscribe trigger.
  

Local fix

• Remove the duplicate database entries by hand.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * Users using an application that subscribes to push           *
  * notifications from an event source that declares a callback  *
  * for an onDeviceSubscribe trigger.                            *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * In the case of sending a push notification to an application *
  * that has been un-installed from a device (in which case the  *
  * push notifications service removes it from its own records), *
  * the following message is received in Worklight (in the       *
  * Eclipse Worklight console), for example for GCM:             *
  * FWLSE0087I: GCM: Device registration ID                      *

  * GEfFPdeqSvpMzm0bevt461lhez_44Fm7Nbxx5DEyPA rejected by the   *
  * server (NotRegistered). Subscription deleted.                *
  * However, in fact Worklight does not delete the subscription  *
  * from the database, the subscription remains in the           *
  * NOTIFICATION_DEVICE table (because there was an internal     *
  * error while calling onDeviceSubscribe). This will lead to    *
  * possible double-notifications if the end-user                *
  * installed-subscribed-uninstalled-reinstalled-subscribed, in  *
  * the application.                                             *
  * This will only happen in the case where the subscribed event *
  * source declares a callback for the onDeviceSubscribe trigger *
  * (in the adapter xml file).                                   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * -                                                            *

  from the database.
