Michael Lipp commented on TOMAHAWK-858:
---------------------------------------
Thought about it again. Actually, the setXXX methods always set the local
value, thus overriding any value binding. Therefore the *real* patch is to
modify broadcast:
public void broadcast(FacesEvent event) throws AbortProcessingException {
if (event instanceof TabChangeEvent)
{
TabChangeEvent tabChangeEvent = (TabChangeEvent)event;
if (tabChangeEvent.getComponent() == this)
{
ValueBinding vb = getValueBinding("selectedIndex");
if (vb == null) {
setSelectedIndex(tabChangeEvent.getNewTabIndex());
} else {
vb.setValue(getFacesContext(),
new Integer(tabChangeEvent.getNewTabIndex()));
}
getFacesContext().renderResponse();
}
}

> Key: TOMAHAWK-858
> URL: https://issues.apache.org/jira/browse/TOMAHAWK-858
> Project: MyFaces Tomahawk
> Issue Type: Bug
> Components: Tabbed Pane
> Affects Versions: 1.1.5-SNAPSHOT
> Environment: WinXP, JDK 1.5, JBoss 4.0.4 GA, Facelets
> Reporter: Michail Jekimov
> Attachments: HtmlPanelTabbedPane.class, HtmlPanelTabbedPane.java
>
>
> The following works fine:
> <t:panelTabbedPane styleClass="panelTabbedPane"
> activeTabStyleClass="activeTab"
> inactiveTabStyleClass="inactiveTab"
> tabContentStyleClass="tabContent"
> selectedIndex="3"
> disabledTabStyleClass="inactiveTab" serverSideTabSwitch="false">
> <t:panelTab id="tab1" label="Tab 1">
> <ui:include src="/Tab1.xhtml" />
> </t:panelTab>
> <t:panelTab id="tab2" label="Tab 2">
> <ui:include src="/Tab2.xhtml" />
> </t:panelTab>
> <t:panelTab id="tab3" label="Tab 3">
> <ui:include src="/Tab3.xhtml" />
> </t:panelTab>
> </t:panelTabbedPane>
> I.e. the tab tab3 is visible when the tabbed pane is rendered. But if I set
> selectedIndex="#{myBean.selectedTabIndex}" then tab1 is always visible first,
> regardless of the value of myBean.selectedTabIndex
