RE: Event handling and swapping panels
Thanks. But what does OuterPanelClass refer to in my example?
I don't think either of these are right:
MyEmptyPanel.this.panel.replaceWith(replacement);
-or-
MyPage.this.panel.replaceWith(replacement);
Or do I need to define workingPanel as a private member of my page class and
then have:
MyPage.this.workingPanel.replaceWith(replacement);
MyPage.this.workingPanel = replacement;

RE: Event handling and swapping panels
Only problem is that it is not working. The panels never update to the new
panels. I can see that the onEvent fires as the javascript alert is shown.
But the javascript is only shown the first time I click a link. After the
first click, all the links call their onClick method and send the event out but
the event is never picked up. Does every panel need to have its own onEvent
method to listen for the events.
If so, I think the old method of handling ajax is going to be easier.

Re: Event handling and swapping panels
yes, every panel has to have onevent. in this case the panel that has
onevent is replaced by a panel that doesnt, so it no longer receives
the event. what you should do is put the onevent in the page, not in
the panel.

Re: Event handling and swapping panels
Unless you override the onEvent method for each panel (MyPanel1, MyPanel2 and
MyPanel3) ,
only the first working panel will manage the event.
one solution would be :
public class Admin extends WebPage {
@Override
public void onEvent(IEvent? event) {
super.onEvent(event);
if (event.getPayload() instanceof MyPanelEvent) {
MyPanelEvent yourEvent = (MyPanelEvent) event.getPayload();
showSelectedPanel(yourEvent.getTarget(), yourEvent);
} else {
// your code here
}
}
private void showSelectedPanel(AjaxRequestTarget target, MyPanelEvent e) {
Component replacement;
switch (e.getType()) {

Only problem is that it is not working. The panels never update to the new
panels. I can see that the onEvent fires as the javascript alert is shown.
But the javascript is only shown the first time I click a link. After the
first click, all the links call their onClick method and send the event out
but the event is never picked up. Does every panel need to have its own
onEvent method to listen for the events.
If so, I think the old method of handling ajax is going to be easier.
