We discuss the importance of inelasticity in the P-wave {pi}{pi} amplitude on the Dalitz distribution of 3{pi} events in J/{psi} decay. The inelasticity, which becomes sizable for {pi}{pi} masses above 1.4 GeV, is attributed to KK{yields}{pi}{pi} rescattering. We construct an analytical model for the two-channel scattering amplitude and use it to solve the dispersion relation for the isobar amplitudes that parametrize the J/{psi} decay. We present comparisons between theoretical predictions for the Dalitz distribution of 3{pi} events with available experimental data.
