Abstract: Let $X$ be a completely regular Hausdorff space, $ \mu $ a positive, finite Baire measure on $X$, and $E$ a separable metrizable locally convex space. Suppose $ f: X \to E $ is a measurable mapping. Then there exists a sequence of functions in $ C_{b}(X) \otimes E $ which converges to $f $ a.e. $[ \mu] $. If the function $ f $ is assumed to be weakly continuous and the measure $ \mu $is assumed to be $ \tau$-smooth, then a separability condition is not needed.
