I have a method that uses the response of an asynchronous call. Here is it:
for(int i=0;i<listeOfApplications.size();i++) {
menuItem.setText(listeOfApplications.get(i).toString());
MenuSetup ms1 = new MenuSetup(menu, menuItem);
ms1.getSubMenus();
}
During each iteraton, the getSubMenus() method has to be called. The
getSubMenus() is as follows:
public void getSubMenus(){
try {
con.getSubMenus(menuItem.getText(), new AsyncCallback<ArrayList<String>>() {
public void onFailure(Throwable caught) {
System.out.println("Remote Procedure Call apps- Failure");
}
public void onSuccess(ArrayList<String> result) {
Menu men = new Menu();
for(int i =0; i< result.size();i++)
{
MenuItem menuItem1 = new MenuItem(result.get(i));
menuItem1.addSelectionListener(menuListener);
men.add(menuItem1);
}
menuItem.setSubMenu(men);
menu.add(menuItem);
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
Now, for each iteration on the listeOfApplications list, the getSubMenus() is
to be called. But what happens here is that all the iterations take place
before the getSubMenus() method starts execution.
Is there a way to know on the client side that the execution of the
asynchronous call has ended? I need this to control my iterations. I have tried
wait(); but it does not work. Help!!!

Hi,
Doing synchronous call is globally a bad idea. What is your exact
need?
