Here some peudocode how I would solve it:
UpdateRows[] rows = getUpdateRows();
// lock GUI, etc.
callUpdate(rows, 0);
private callUpdate(UpdateRows[] rows, int currentIndex){
showCurrentProcessedRow(rows, currentIndex);
ServerServices.Util.getInstance().performRowUpdate(rows[currentIndex], new
AsyncCallback() {
public void onSuccess(Object result) {
currentIndex++;
if (currentIndex < rows.length){
callUpdate(rows, currentIndex);
return
}
showSuccessMessage();
unlockGUI();
}
public void onFailure(Throwable caught) {
showErrorMessage(caught);
unlockGUI();
}
});
}
}
