This is caused by using the old 8.1.x version of GWT Designer. This is also discussed in the release notes...
http://code.google.com/webtoolkit/release-notes.html#Release_Notes_2_2_0 Uninstall GWT Designer 8.1.x (which is not compatible with GWT 2.3.1) and use the version of GWT Designer integrated with GWT/GPE 2.3.1. To uninstall, go to "Help > About > Installation Details > Installed Software", select all of the GWT Designer v8.1.x components (everything with a 8.1.x version tag), and click "Uninstall".
