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.
}
}
