The spatial toolbox supports *non* interactive GRASS commands, so
those bound to the display are not supported. It should not even
appear in the list of avaliable modules.
If you just need to display a GRASS raster you can do it without toolbox.
The fastest way to do so is:
- create an empty file named "wkp.jgrass" in your location (the
extention jgrass counts here)
- then simply drag and drop that file into uDig's catalog
- the first time it will ask you to choose a projection from the usual
list, because uDig is not able to reproduce the projection info from
GRASS' projection file
- once dragged, the location will show you mapsets and raster maps
inside the catalog
Does that help?
