Thanks a lot,
I am going to try with setInnerHTML. Currently though, I am adding the
form via an HTML Widget:
String form = "<form id="qwert" ... </form>"; // the real html is
downloaded in ajax
HTML htmlWidget = new HTML(form);
RootPanel.get().add(htmlWidget);
Shouldn't that be more or less equivalent to using innerHTML?
