I simply parse the component id. Being an iterating component -
Tridindad adds a progressive index while stamping out subcomponents:
public void navigation(ActionEvent event) {
FacesContext fc = FacesContext.getCurrentInstance();
UIComponent actionItem = event.getComponent();
String id = actionItem.getClientId(fc);
int i = id.lastIndexOf(NamingContainer.SEPARATOR_CHAR);
if (i >= 0) {
id = id.substring(0, i);
i = id.lastIndexOf(NamingContainer.SEPARATOR_CHAR);
id = id.substring(i + 1);
int newSelected = Integer.parseInt(id);
.....
This should work well for all Trinidad iterating components, provided
that stamping includesTrinidad components only. Otherwise, the index
can be easily forgotten by Trinidad (then duplicated id warnings),
don't ask me why.

Thank you, your example is great.
However, how do you know what tab has been clicked, so you can act
accordingly on the actionListener?

Francisco,
component tr:navigationPane is an iterating component by itself -
no need for an explicit loop. I do it like this (using Facelets):
<ui:component>
<c:if test="#{bean.visible}">
<t:saveState id="selected" value="#{bean.selected}"/>
<t:saveState id="tabs" value="#{bean.tabs}"/>
<tr:navigationPane id="tabber" hint="tabs"
value="#{bean.tabModel}" var="tab" styleClass="navigator">
<f:facet name="nodeStamp">
<tr:commandNavigationItem text="#{tab.label}"
actionListener="#{bean.navigation}"
id="tab" selected="#{cx:isSelected(bean, tab)}"
icon="#{tab.icon}"/>
</f:facet>
</tr:navigationPane>
<cx:include src=""
bean="#{bean.componentBean}" container="#{container}tabby:"/>
</c:if>
</ui:component>
Here everythings - from the tab list to the child component to appear
below the tabs - is dynamically taken from a bean.
Tab list and current selection are made persistent across requests by
means of saveState (my beans are only request-scoped).
Hope it helps.

By the way, I'm trying to populate dinamically either a
panelTabbed or
a navigationPane.
When using ui:repeat, panelTabbed renders incorrectly (no content
appears) and this is shown on the logs:
WARNING: Only tr:showDetailItem is allowed as child of tr:panelTabbed.
When using ui:repeat and navigationPane, an exception is thrown:
SEVERE: Warning: illegal component hierarchy detected, expected
UIXCommand but found another type of component instead.
java.lang.ClassCastException
: com.sun.facelets.component.UIRepeat
I'm going to try my luck with JSTL now, nevertheless if you know of a
solution, do tell :)

Simon and Matthias,
thank you for clearing my doubt. By the way, if I may leave the
suggestion, it would be cool if panelTabbed had alternative ways for
presentation, much like navigationPage.
As far as the wiki, I've added the missing entry to the page for
completeness, although obviously it may still be incomplete.

Francisco,
we started a wiki, containing infos like this, in the past,
but never updated it.
