I'm confused but it seems that the gofer in pier1.2 does not understand the same protocol than the one in latest seaside. Is there a way to fix that ?

Yeah, these images are all based on older Pharo versions. I plan to create updated versions as soon as Pharo 1.0 is out. To update Gofer you can try: Gofer upgrade Lukas -- Lukas Renggli http://www.lukas-renggli.ch
