Hi Ronald, "kukeltje" wrote : Each task completed updates the global variable, so the last task completed is the one that 'wins'. This means there will be a data-loss. E.g. A modifies its local replica of a global context variable, and B modifies also its replica. But if B approves later, modifications of A will be lost, only B's local replica will be stored back globally. Am I right?
