electroosmotic velocity BC and reaction force

I am working on a model for fluid flow around a circular cylinder(similar to the tutorial from the comsol model library). In difference to that I am applying the electroosmotic velocity boundary condition at the wall. Right now I want to use the reaction force operator (reacf) to evaluate the drag and lift coefficients at the cylinder.
When I look at the values for reacf it is zero all the time. So does anybody know if the reaction force operator does not work with the electroosmotic velocity BC?
I would really appreciate your kind assistance for this issue.
