We would like to click on a button in order to save a form. This submit button has to execute an insert or update via JPA.

At the end, we would like to show a notification with the result of operation then launch a redirection.

How to manage a Client.showNotification then a Executions.sendRedirect ? How can we waiting the end of notification before sendRedirect ?

Thank you.

I do implement the same way. But after save, will show the notification at the top and immediately it will be back to listing screen. Putting messagebox for saving it is not acceptable because they have click the ok button.

Yeah, messagebox is not ok for the client. I try to put the sendredirect but the notify action doesn't work. I try with a Thread.sleep but all are frozen....

So here my solution.

  1. Add a specific binder into zul (binder="@init(queueName='redirectQueue', queueScope='session')")
  2. Launch a Client.showNotification
  3. Create a new thread
  4. Lookup EventQueue (EventQueues.lookup("redirectQueue", Executions.getCurrent().getSession(), true))
  5. Pass it to the thread
  6. In the thread, launch a Thread.sleep then a new GlobalCommand on the EventQueue (with url in params)
  7. In GlobalCommand, realize the Executions.getCurrent().sendRedirect with url passed in args

But works for me. Here is the sample piece of code

try {
        CRUDService.Save(this.selectedRecord);
        Infrastructure.showSuccessmessage();
        goBack();

public static void showSuccessmessage() {
    Clients.showNotification(Consts.SUCCESS_MESSAGE,
            Clients.NOTIFICATION_TYPE_INFO, null, "top_center", 4100);
}
/* Start: Auto Close Notification message box

/* ----------------------------------------------------------------------------------------------------------------------- */

/* Start: Auto Close Notification message box /* ----------------------------------------------------------------------------------------------------------------------- */ .z-notification .z-notification-cl,.z-notification .z-notification-cnt { height: 30px; width: 250px; }

.z-notification-info .z-notification-cl { background-color: #ADD8E6; }

.z-notification .z-notification-cl { color: white; }

.z-notification .z-notification-cnt { background: none repeat scroll 0 center transparent; font-size: 14px; font-weight: normal; margin: 0 !important; overflow: hidden; }

.z-notification-info .z-notification-cl { background-color: #da5867; }

goBack = sendRedirect ? Are you with Zk 6, in MVVM architecture ? So, you can see the notification during 4s before the redirection ?

Yes i am using zk 6 with MVVM. But not with redirect, instead of that Executions.createComponents.

You can see example here. Follow the steps

  1. Click this Link

  2. In the Top Menu, Click MVVM

  3. Next click CRUD Form.

  4. You can see "MVVM CRUD Without DB Connection". In the action column, you can download the source code, or you can run or you can look the documentation.

Have you ever tried Clients.showNotification() methods with parameter duration (in ms)?

void org.zkoss.zk.ui.util.Clients.showNotification(String msg, String type, Component ref, int x, int y, int duration)

void org.zkoss.zk.ui.util.Clients.showNotification(String msg, String type, Component ref, int x, int y, int duration, boolean closable)

void org.zkoss.zk.ui.util.Clients.showNotification(String msg, String type, Component ref, String position, int duration)

maybe that can help.
