I tried your advice and I keep the timer behavior "outside" the tab, in
MyTabbedPanel. In the refreshable panel I register a listener with
MyApplication.get().addRefreshableComponent(Duration,Component). When I
select the tab with the refreshable panel all works fine but when I switch
the tab I received the same "PageExpiredException: No behavior listener
found with behaviorId".
Did I do something wrong or I misunderstood you?
Below is the java code:
public class MyTabbedPanel extends AjaxTabbedPanel {
private static final long serialVersionUID = 1L;
private List<AbstractAjaxTimerBehavior> ajaxTimerBehaviors;
public ImageTabbedPanel(String id, List<ITab> tabs) {
super(id, tabs);
ajaxTimerBehaviors = new ArrayList<AbstractAjaxTimerBehavior>();
}
@Override
protected WebMarkupContainer newLink(String linkId, final int index) {
List<? extends ITab> tabs = getTabs();
// check for usage of our custom class, if it is not our class,
// add as image empty container - this way you can use image
only in tabs
you want
ITab currentTab = tabs.get(index);
if (currentTab instanceof ImageTab) {
final ImageTab imageTab = (ImageTab) currentTab;
return new ImageTabLink(linkId, imageTab.getImage()) {
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target) {
removeAjaxTimerBehaviors();
clearRefreshableComponents();
setSelectedTab(index);
createAjaxTimerBehaviors();
addAjaxTimerBehaviors();
target.addComponent(MyTabbedPanel.this);
}
};
} else {
WebMarkupContainer link = super.newLink(linkId, index);
link.add(new
WebMarkupContainer("image").setVisible(false));
return link;
}
}
private Map<Duration, List<Component>> getRefreshableComponents() {
return MyApplication.get().getRefreshableComponents();
}
private void clearRefreshableComponents() {
getRefreshableComponents().clear();
}
private void createAjaxTimerBehaviors() {
final Map<Duration, List<Component>> refreshableComponents =
getRefreshableComponents();
Set<Duration> durations = getRefreshableComponents().keySet();
for (final Duration duration : durations) {
AbstractAjaxTimerBehavior behavior = new
AbstractAjaxTimerBehavior(duration) {
private static final long serialVersionUID = 1L;
@Override
protected void onTimer(AjaxRequestTarget
target) {
List<Component> components =
refreshableComponents.get(duration);
for (Component component : components) {
target.addComponent(component);
}
}
};
ajaxTimerBehaviors.add(behavior);
}
}
private void addAjaxTimerBehaviors() {
for (IBehavior behavior : ajaxTimerBehaviors) {
add(behavior);
}
}
private void removeAjaxTimerBehaviors() {
for (AbstractAjaxTimerBehavior behavior : ajaxTimerBehaviors) {
behavior.stop();
remove(behavior);
}
ajaxTimerBehaviors.clear();
}
}
