We consider a driven diffusive system with two kinds of particles, A and B, coupled at the ends to reservoirs with fixed particle densities. To de. ne stochastic dynamics that correspond to boundary reservoirs we introduce projection measures. The stationary state is shown to be approached dynamically through an infinite reflection of shocks from the boundaries. We argue that spontaneous symmetry breaking observed in similar systems requires placing effective impurities at the boundaries and therefore does not occur in our system. Monte Carlo simulations confirm our results.
