Is range of the induced vector measure of a Riemann-Pettis integrable function relatively compact in X?

A function $f\in X^{[a, b]}$ is said to be Riemann-Pettis integrable if $x^* f$ is Riemann integrable for each $x^*\in X^*$ and if for each interval $I\subset [a, b]$, there is a vector in $x_I\in...
