Symptoms

MPOS currently supports a feature called "Seamless Offline" which will take the MPOS into offline mode if Retail Server calls fail due to connectivity issues. However, the "Seamless Offline" happens on the very first request to the Retail Server that fails and happens without any user notification. This sometimes causes issues as the cashier is unaware that the MPOS has switched to offline and can happen frequently in scenarios where connectivity to the Retial Server is less stable.

Resolution

The following features were implemented to make the MPOS feature more stable:

1. Make POS seemless offline configurable.
2. Add retry logic as a configuration.
3. Dialog to confirm that user wants to switch to offline mode.
4. Do not allow to switch back online, if we are logged out to ensure upsert shift does not fail.
5. Upload and download data calls, if failed due to network error, should not try switch POS into offline mode.


Description of fix *: 
1 and 2. Adding a check box in AX for the retry count and seamless offline control in the Offline Profile form.
3. Added the dialog to prompt user if he is sure he wants to switch to offline mode.
4. Put a condition to not allow switchConnectionToOnlineIfDue() if we are logged out.
5. Does not allow onlineRequests (contains all upload and download data requests) to switch POS into offline mode.
