Form submit event in GWT (and GQuery) is causing IncompatibleRemoteServiceException

Question

A form submit event in GWT and GQuery is causing an IncompatibleRemoteServiceException. This project includes GQuery (GWT version of JQuery) which is used to call the form submit. Here's the code for it. The event is inserted in onmoduleload function:

$("#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));
        }
    });
    }
});

The exception shows up whenever the submit button is clicked. If the server call is made from outside the submit event, it works fine - otherwise public void onFailure(Throwable caught) is executed. Here's the exception:

Most possible reason is jars version.

Check if the gwt-servlet.jar is uptodate. The gwt-user.jar and gwt-servlet.jar must have the same version.

see A discussion here on the same.

I don't see a version number on my GWT-servlet.jar. Do you know how to find that? – EternallyCurious May 04 '13 at 10:35
which version of gwt you are using ? – Suresh Atta May 04 '13 at 10:44
My GWT-dev.jar and GWT-user.jar say 2.4.0 – EternallyCurious May 04 '13 at 11:18
Yeah I changed it but it still doesn't work. I honestly don't think its the version. Any other possibilities? Something with GQuery maybe? – EternallyCurious May 04 '13 at 14:46
