Re: Populate Dropdowns

You can try something like this:

ListBox box = new ListBox();
box.setEnabled(false);
box.addItem("loading...");

service.getData(new AsyncCallback{public void onSuc(loadData(result));

public void loadData(ArrayList<Data> list){
box.clear();
for(Data d:list){
box.addItem(d.getName());
}
box.setEnabled(true);
}

basically just add the SingleSelect ListBox to the UI with a message
to the user and disable it

then when the request returns, clear the box, enable it, and add items

Maybe your problem isn't that easy though...
