The materials for the « Building web based GIS applications with GeoExt » tutorial we gave at FOSS4G2010 in Barcelona is available for download at http://presentations.opengeo.org/2010_FOSS4G/gx-tutorial.zip. There’s a readme.txt file in there for instructions.
Thanks to my mates for this presentation: Andreas Hocevar (OpenGeo) and Yves Jacolin (Camptocamp).
I attended your (very good) tutorial at FOSS4G. Thank you for this download!
