This is an announcement for the paper "The McShane integral in weakly compactly generated spaces" by Antonio Aviles, Grzegorz Plebanek, and Jose Rodriguez. Abstract: Di Piazza and Preiss asked whether every Pettis integrable function defined on [0,1] and taking values in a weakly compactly generated Banach space is McShane integrable. In this paper we answer this question in the negative.
