GWT（和GQuery）中的表单提交事件导致IncompatibleRemoteServiceException

GWT中的表单提交事件和GQuery导致IncompatibleRemoteServiceException。该项目包括用于调用表单提交的GQuery（JQuery的GWT版本）。这是它的代码。事件被插入onmoduleload函数：GWT（和GQuery）中的表单提交事件导致IncompatibleRemoteServiceException

$("#search_form").submit(new Function(){ 
    public void f() { 
    QueryRequest query = new QueryRequest(); 
    String keywords = $("#keyword_search_box").val(); 
    query.setKeywords(keywords); 
    greetingService.search(query, new AsyncCallback<QueryResponse>() { 

      @Override 
      public void onFailure(Throwable caught) { 
       Window.alert(COUNLDNT_REACH_SERVER); 
     } 

     @Override 
     public void onSuccess(QueryResponse result) { 
      $("#page").add(renderResponse(result)); 
     } 
    }); 
    } 
});

无论何时单击提交按钮，都会显示异常。如果服务器调用是从提交事件之外完成的，那么它可以正常工作 - 否则执行public void onFailure（Throwable）。这里的例外：
