asynchronous beer story :)

You are trying to make an asynchronous call into a synchronous one.
Its a question that has been asked many times, and the answer is -
don't try to do it. Read the document at -
http://code.google.com/webtoolkit/doc/1.6/DevGuideServerCommunication.html#DevGuideGettingUsedToAsyncCalls

I have this code, which sends a call to the server. This call takes a
few seconds to complete.
I should not run System.out.println until the call ends.
I do this? How I wait for the server?
thanks
[CODE]
String value=nothing;
BDServiceAsync service = GWT.create(BDService.class);
service.myCall(text, new AsyncCallbackMapString,String(){
public void onFailure(Throwable caught) {
}
public void onSuccess(MapString,String result) {
// This takes a few seconds to complete.
value=hola;
}
});
// should wait for the call to the server
System.out.println(value=+value);
[/CODE]

Re: Wait for server call
Sorry, I will relaunch the question
[CODE]
// At this point I built the user interface.
// I have a combo and others elements...
MapString,String comboValues = new MapString,String()
BDServiceAsync service = GWT.create(BDService.class);
service.fillCombo(text, new AsyncCallbackMapString,String
(){
public void onFailure(Throwable caught) {
}
public void onSuccess(MapString,String result) {
// I access to the database for data. to get de
combo values.
comboValues = result;
}
});
// should wait for the call to the server
combo.setValues(comboValues);
// the flow continues
[/CODE]
Sorry for my english!

Re: Wait for server call
If I do it, the user interface shows in browser before the combo fill
values... :(
The user interface show a empty combo.
