This test fails as the event handler is called twice...
public void testFoo() {
Element body = RootPanel.getBodyElement();
Element div = DOM.createDiv();
div.setId(DOM.createUniqueId());
body.appendChild(div);
ListBox lb = new ListBox();
RootPanel.get(div.getId()).add(lb);
lb.addItem("a");
lb.addItem("b");
final List<String> l = new ArrayList<String>();
lb.addChangeHandler(new ChangeHandler() {
@Override
public void onChange(ChangeEvent event) {
l.add("aa");
}
});
lb.setSelectedIndex(1);
assertEquals(0, l.size());
}
Am I doing something stupid? I get the same result in dev and prod
modes. The stack trace is horribly complicated so I'm not that keen to
dive in and try and debug this...
