Hello Andrea, I did the following test: 1. Start JGrass 2. New map 3. Add a raster layer "thin" 4. I rename a layer with the command:
grass g.rename.exe rast=thin,renamethin Console output Rename raster <thin> to <renamethin> It's ok. 5a. Close JGrass 6a. Start JGrass 7a. Add the raster "renamethin", it's ok. And there is the error "Non è stato trovato nessun renderer in grado di renderizzare il piano" on "thin" raster because this dont'exist. If 5a. Add the raster "renamethin", isn't ok, there is "Non è stato trovato nessun renderer in grado di renderizzare il piano" on "renamethin" Hi Giuseppe, > I use this brach JGrass src: > > https://svn.dev.cocos.bz//svnroot/jgrass/jgrass3.0/branches/jgrass4udig1.1.x/trunk/ > > and uDig 1.1.1 lib on windows xp. > > I can try.
