We study the resistive transition in Josephson-junction arrays at f = 1/2 flux quantum per plaquette by dynamical simulations of the resistively-shunted-junction model. The current-voltage scaling and critical dynamics of the phases are found to be well described by the same critical temperature and static exponents as for the chiral (vortex-lattice) transition. Although this behavior is consistent with a single-transition scenario, where phase and chiral variables order simultaneously, two different dynamic exponents result for phase coherence and chiral order.
