Modal window update once opened
I am new to Wicket and am having difficulty figuring out how to update a
modal window without closing it and reopening it. I've seen similar posts
but have not found the answer as of yet. We are using Wicket 1.4.7. The
scenario is that I have a ModalWindow component that is part of form. The
ModalWindow is acting as a progress dialog and displays the step and some
information in the title and a message field. On the parent form that
contains the modal window, I have an AjaxSelfUpdatingTimerBehavior with a
simple state machine. I want to keep the modal window open and change the
title and message text as things progress in the state machine. I've tried
a number of things, but I cannot get the text or title to update on the
modal window. The basic code that I have is:
/* HTML for ModalWindow */
<wicket:panel>
<table width="100%">
<tr>
<td></td>
</tr>
</table>
</wicket:panel>
/* the modal window is already displayed when the timer fires the first time
*/
timerBehavior = new
AjaxSelfUpdatingTimerBehavior(Duration.seconds(REFRESH_RATE))
{
private static final long serialVersionUID =
4618003750684232624L;
@Override
protected void
onPostProcessTarget(AjaxRequestTarget timerTarget)
{
if (state == DeviceProgressEnum.PREPARE)
{
/* lines deleted */
state = DeviceProgressEnum.PREPARE_WAIT;
modalWindow.setMessage("Please wait
while we prepare...");
modalWindow.setTitle("Step 1 of 3");
modalWindow.show(timerTarget);
/* also tried:
timerTarget.add(modalWindow);
}
/* lines deleted */
}
How can I update a modal window once it has been opened? What am I doing
wrong?
Thanks!

Sounds weird about two divs with same id.
At first glance, it looks like a bug.
Can someone confirm ?

Thank you for your quick reply.
I had the modalWindow.setOutputMarkupId(true) as well as on the message
label on the modalWindow. I tried the timerTarget.addComponent(modalWindow)
in the onPostProcessTarget. No luck.
When I look at the rendered HTML, I see two different content area divs
for the modal window and both have the same id. One is rendered as part of
the parent form with display:none, and the other is rendered in a bunch of
divs for the modal window outside of the parent form. The content of the
first div with the display:none is changed with the new message label. The
content of the content div in the modal window, which is displayed, is not
changed. Hmm.
Is there something special about refreshing the content of the
modalWindow versus other components?

In onPostProcessTarget :
timerTarget.add(modalWindow)
You have to add components you are refreshing to the AjaxRequestTarget instance.
Don't forget to set markupId to true for modalWindow
modalWindow.setMarkupId(true);
when you add it to the parent component.
