IBM MobileFirst Platform Foundation Interim Fix README for 7.1
IBM MobileFirst Platform Foundation Interim Fix README for 7.0

APAR status

• Closed as program error.

Error description

• There is a synchronization process that iterates the
  collections of a JSONStore and pushes the dirty data to the
  database via an SQLAdapter. The application just seems to
  stop/hang and native calls (JSONStore, Cordova plugins,
  Adapters) don't return.
  

Local fix

• There is an an official fix from the Apache community:
  
  https://issues.apache.org/jira/browse/CB-7735
  
  That can temporarily be replaced in the project which contains
  the "www/default/worklight/cordova.js"

  * PROBLEM DESCRIPTION:                                         *
  * The application gets stuck or hangs when you make many calls *

  * RECOMMENDATION:                                              *

  ****************************************************************
  

Problem conclusion

• The problem was due to an issue with the javascript to native
  bridge in Cordova. The request never got sent across the bridge
  so it never reached the native side.
