Menu
I need to get title of currently active tab inside my TabView. TabView is constructed with dynamic number of tabs with listener attached to "tabChanged":
<p:tabView value="#{bean.list}" var="listItem">
<p:ajax event="tabChange" listener="#{listenerBean.onChange}" />
<p:tab title="#{listItem.stringProperty}">
</p:tab>
</p:tabView>
The problem is that TabChangeEvent object received by onChange(TabChangeEvent event) always contains first tab instead of the active one.
public void onChange(TabChangeEvent event) {
event.getTab().getTitle(); //allways returns title of first tab
}
This behavior is only true for dynamic number of tabs in TabView if I define each tab explicitly, TabChangeEvent works fine.
Any suggestions? Thanks.
I use PrimeFaces 3.5 with JSF2.1 and Servlets 2.5

The following minimal example worked for my like a charm by printing the title of the tab to activate every time I click on it:
