@Alberto
I tested the latest NB (4801) and the bug is still evident, even if I don't
have the NPE.
The test was this
a) Open a project (with layers and Sextante layers)
b) load a new sextante raster OR create a new sextante raster and save it
c) Save the project file
d) when I reload the project the sextante raster b) is not loaded.
I did a test on the same project file using a pre-OJ1.9 version (4560)
and it works fine (reloading the project file, the new raster is displayed)
