Grouped bwplots?

Dear list, I am sorry for asking you this, but I am trying to do again what I thought I have done before, although this time it does not work. So, given the data set:
testdf <- data.frame(grfak=sample(c("One","Two"),size=100,replace=TRUE), panfak= sample(c("Yes","No"),size=100,replace=TRUE), xfak= sample(c("Yep","Nope"),size=100,replace=TRUE), d=rnorm(100))
I would like to do:
bwplot(d ~ xfak | panfak,data=testdf, groups= grfak)
where the groups argument makes a difference (as in dividing each box into two by group). Is this possible to do? If so, what I am doing wrong?
An alternative approach is to use ggplot2:
install.packages("ggplot2")
library(ggplot2)
qplot(xfak, d, data=testdf, facets = ~panfak, fill = grfak, geom="boxplot")
