This sounds vaguely like a problem scala-gwt ran into in the scala-ized GWT showcase with classes that were shared across split points. The problem there was with undefined class literals, which is different from what you're seeing, but might be related. Can you apply this patch to a local GWT trunk build and see if it helps: http://gwt-code-reviews.appspot.com/1513803/ - Stephen -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
