Your code is not reproducible (but full of irrelevant details).
All the grid layout stuff is commented out, so I am not sure what
you expect this code to do.

Anyway, you are probably missing some upViewport / popViewport
calls, since the following does what I would expect:



library(lattice)
library(grid)

p <- xyplot(1 ~ 1)

grid.newpage()
pushViewport(viewport(layout = grid.layout(2, 2)))

pushViewport(viewport(layout.pos.col=1, layout.pos.row=1))
print(p, newpage = FALSE)
popViewport(1)

pushViewport(viewport(layout.pos.col=2, layout.pos.row=2))
print(p, newpage = FALSE)
popViewport()
