A recent study indicates that it is okay to install foam sheathing over OSB. We have been doing it for about 40 years without problems. Having said that, the caveats are the OSB needs to be able to dry to the inside (no interior plastic vapor barriers), be careful with window-to-wall interfaces, and to prevent hydrostatic pressure issues with claddings.
