Hi all!, I've a little problem upgrading my code from 1.5.3 to 1.6.4. I've an AccountManager class that manages the accounts and when a change is done it fires an event to all the components to update its list of accounts.
AccountManager: private ChangeListenerCollection changeListeners; public void addChangeListener(ChangeListener listener) { if (changeListeners == null) { changeListeners = new ChangeListenerCollection(); } changeListeners.add(listener); } public void removeChangeListener(ChangeListener listener) { if (changeListeners != null) { changeListeners.remove(listener); } } private void fireChangeEvent() { if (changeListeners != null) { changeListeners.fireChange(accountMainPanel); } } private void loadAccounts() { AccountRemote.Util.getInstance().getAllAccount(new DefaultCallback() { @SuppressWarnings("unchecked") public void onSuccess(Object result) { if (result != null) { accounts = (List<Account>)result; // Save the accounts accountList.clear(); accountsHM.clear(); for (Account account : accounts) { accountList.addItem(account.getAccountName()); // Save the accounts accountsHM.put(account.getAccountName(), account); } // Update the list of the accounts in all clients fireChangeEvent(); } } }); } And in the clients I have this code: // ChangeListener to update the account list whenever an account change is done. ApplicationParameters.getInstance().getApplication ().getAccountManager().addChangeListener(new ChangeListener() { public void onChange(Widget sender) { // Update the accounts setFilterAccounts(ApplicationParameters.getInstance().getApplication ().getAccountManager().getAccounts()); } }); Now I'm trying to update this code to use EventHandlers but I've no idea what I should change. I've try with: public HandlerRegistration addChangeHandler(ChangeHandler handler) { return addDomHandler(handler, ChangeEvent.getType()); } But I cann't control when fire the event, I mean, when I change something the event is fired and the clients are updated even if it is not necessary. Please, could someone bring me to the light :-). Thanks a lot. Regards, Iván. P.S: Excuse me for me poor english. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
