Problem solve.
It not possible to use directly raster layers coming from reclassified 
work for example and automatically charge in the TOC of GvSIG, the name 
are not properly understand by Sextante Raster calculator tool.

You need to recharge the proper raster layers with their original name 
instead of the one automatically charge in the TOC by GvSIG at the end 
of any reclassication or raster calculator step.
