I created a PanelMenu in a page and then bind to a managed bean, then create sub menu groups and items dynamically in code. Like this:
1. Part of mypage.xhtml
---------------------------------------------
<rich:panelMenu style="width:200px" mode="ajax" binding="#{subscriptionList.panelMenu}"
iconExpandedGroup="disc" iconCollapsedGroup="disc"
iconExpandedTopGroup="chevronUp" iconGroupTopPosition="right"
iconCollapsedTopGroup="chevronDown" iconCollapsedTopPosition="right" id="panelMenu"/>
------------------------------------------------
2. Part of SubscriptionList.java
-----------------------------------------------
public class SubscriptionList extends BasePage implements Serializable {
...
private HtmlPanelMenu panelMenu;
public HtmlPanelMenu getPanelMenu() {
System.out.println("GetPanelMenu");
if (panelMenu == null) {
panelMenu = new HtmlPanelMenu();
}
panelMenu.getChildren().clear();
List groups = getPanelMenuGroups();
menu.getChildren().addAll(groups);
return panelMenu;
}
public void setPanelMenu(HtmlPanelMenu panelMenu) {
this.panelMenu = panelMenu;
}
public SubscriptionList() {
}
protected List getPanelMenuGroups() {
...
return groups;
}
}
----------------------------------------------------------
These code work correctly. The problem is that when I updated the menu items in other places I need to update the PanelMenu also, but I found that the function "getPanelMenu()" was called only once in one session. It seems that the binding-value was stored somewhere in the current session. So, How can I modify this object? Is there other ways to update the component dynamically?
Thanks!
