Re: Dynamically generated HTML and GWT

I think you kind of misuse the *.wrap() method. They are meant to be used with static html pages that you want to enhance with GWT.

I think what you really want for now is to extend Widget and overwriting onBrowserEvent(), e.g.

MyServerFormWidget extends Widget {

  

  MyServerFormWidget() {

    setElement(Document.get().createDivElement());

    sinkEvents(Event.ONCLICK);

  }

  public void setServerGeneratedHtml(String html) {

    getElement().setInnerHTML(html);

  }

  @Override

  public void onBrowserEvent(Event event) {

    super.onBrowserEvent(event);

    int eventType = DOM.eventGetType(event);

    if(eventType == Event.ONCLICK) {

       //check event target element, if its the submit button

       if(formSubmitButtonHasBeenClicked(event)) {

          event.preventDefault();

          onSubmitClickIntercepted();

       }     

    }

  }

  private void onSubmitClickIntercepted() {

    //do your stuff, e.g. read form data and fire higher level events like fireEvent(new SubmitEvent(formData)); so you could use GWT-RPC/RequestFactory/RequestBuilder to send the form data to the server. That way you don't have to write Servlets directly.

  }

}
