We use the Dalitz-plot analysis technique to measure the resonant substructure in this final state and observe \\rho\\pi and non-resonant contributions by fitting for their amplitudes and relative phases. We describe the pipi S-wave with a K-matrix formalism and limit this contribution to the rate to be < 2.5% @95% confidence level, in contrast to the large rate observed in D+ -> pi+pi-pi+ decay.
