[Aurélien DUMAINE <aurelien.dumaine@xxxxxxx>]

This is the basic logic. In reallity orders are also put in client Js DB
(in case of server disconexion).

Server side :
-----------------
===> update_order(order_id, clien_sync_key, productLines, paymentLines) :
if order_id :
    return DELTED_ORDER to the client
if (client_sync_key !=0 and order_database_sync_key != client_sync_key) :
    return error 'BAD_SYNCHRO_KEY' to the client
else :
    update_order_in_DB
    generate_new_sync_key
    return new_sync_key to the client

====> get_order_details(order_id):
if order_id doesn't exist :
    return DELTED_ORDER to the client
else :
    return productLines and paymentLines in a json string to the cilent

====> del_order(id, sync_key):
if (client_sync_key !=0 and order_database_sync_key != client_sync_key) :
    return error 'BAD_SYNCHRO_KEY' to the client
else :
    delete_order

Client side :
-----------------
===> On create order : sync_key initialised to 0.

===> On order swithcing(old_order=>new_order) :
the old_order(json order,  including the sync_key) is sent to server
update_pos methode.
If it returns 'BAD_SYNCHRO_KEY', a pop up inform the user that the order
had been modificated on an other POS before he switched order. Last
modifications are lost. He has to reload the order if he want to redo his
modifications.
If it returns DELETED_ORDER we display an informative popup, the order is
removed on client side and we display the next one in the stack.
In other case, we update the synch_key returned by the serverin the client.

Call to server methode get_order_details(new_order_id) : If returns
'DELETED_ORDER', we display an informative popup, the order is removed on
client side and we display the next one in the stack. Else all productLines
and paymentLines of new_order are update from server side

===> On delete order : If sync_key != 0 call to del_order server method. If
BAD_SYNC_KEY is return we display a pop-up, else we destroy the client side
order.


I don't know if it 'll be helpfull.....
