Hallo Freunde, ich entwickle GWT App und wenn ich auf dem Registerkarte in meiner app klicken bekomme ich diesen Fehler:Fehler in GWT: "Typ 'com.extjs.gxt.ui.client.data.BasePagingLoadConfig' konnte nicht 'com.google.gwt.user.client.rpc.IsSerializable" zugewiesen werden
[WARN] deviceGroupServlet: An IncompatibleRemoteServiceException was thrown while processing this call.
com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException: Type 'com.extjs.gxt.ui.client.data.BasePagingLoadConfig' was not assignable to 'com.google.gwt.user.client.rpc.IsSerializable' and did not have a custom field serializer. For security purposes, this type will not be deserialized.

Mein Freund hatte similkar Problem und er beschloß, es mit mvn sauber installieren und maven update, aber ich kann das Problem mit diesen Optionen nicht lösen. Was auch immer ich mache, dieser Fehler ist immer noch da. Kann mir jemand helfen?
