Hi,
I have a requirement,
// some code here 1
RPC call
// some code here 2
I want to stop any further execution after rpc call till rpc completes. When
RPC call is finished, the control should automatically start executing next
line of code.
I tried Scheduler class but could get into
There have been lots of people ask this question here. The advice you will get
is:
(1) Don't try to do it like that. It's evil.
(2) Embrace asynchrony.
Here's what your code should look like:
// some code here 1
myservice.rpcCall(args, new AsyncCallbackFoo {
public void onFailure(Throwable
Its not possible to stop execution as RPC requests are async. The only thing
you can do is to put your code that has to wait into the onSuccess method of
your RPC call.

To view this
I am making 2 seperate RPC calls.
Whichever is finished first, i would add RootPanel.get(id).add(widget)
into onSuccess.
I can not add same widgets two times in both onSuccess(). So i am out of
mind how to resolve this.
Any logic pls.

I think you'll have to do something like this:
public class MyEntryPoin implements EntryPoint {
private boolean alreadyAddedWidget;
public void onModuleLoad() {
alreadyAddedWidget = true;
MyService service = GWT.create(MyService.class);
service.someCall(args, new
public void onModuleLoad() {
alreadyAddedWidget = true;
Sorry, it should be set to false here

How about:
if (!RootPanel.get(id).contains(widget)) {
RootPanel.get(id).add(widget);
Because of the nature of javascript and web browsers the above call is
inherently thread safe.

There is no contains(widget) available like RootPanel.get(id).contains(
widget).

True its WidgetCollection that has a 'contains' method but a
RootPanel.get returns a RootPanel object which is a sub-class of
ComplexPanel.
ComplexPanel has a getWidgetIndex methods which return -1 for
getWidgetIndex(Widget) and null for getWidgetIndex(HasWidget) when the
requested object
You could always do the following
boolean alreadyAdded = false;
void addWidget(Widget widget) {
if (!alreadyAdded) {
alreadyAdded = true;
RootPanel.get().add(widget);
}
}
and then call addWidget() in each onSuccess(); first caller wins.
