Tab selection problem in JSF icefaces

I have one tab set as below ,in which i want select dynamic tab using binding in java.

<ice:panelTabSet var="currentTab" partialSubmit="true"  selectedIndex="#{viewBatchBean.tabSelectedIndex}"
            value="#{viewBatchBean.batch.batchConfigurationTabList}"
            tabChangeListener="#{viewBatchBean.showDefaultValueForTab}"
            binding="#{viewBatchBean.panelTabSetRef}">

here i set tab index as below..

  panelTabSetRef.setSelectedIndex(0);

it set tab as per given index but doesn't set focus on it.

Solution

Populating the panelTabSetRef.

//---

for(SomeObject tabConfig : batchConfigurationTabList){
   PanelTab panelTab = new PanelTab();
   // Setting appropriate values in panelTab
   panelTabSetRef.getChildren().add(panelTab);
}

//---

Fetching the PanelTab component from PanelTabSet & processing it accordingly.

List<UIComponent> panelTabs= panelTabSetRef.getChildren();

// Selecting tab to set focus

PanelTab focusTab = (PanelTab) panelTabs.get(tabSelectedIndex);
String tabId = focusTab.getId();

//---

Focus can be set on the selected tab as below using Java Script.

JavascriptContext.addJavascriptCall(FacesContext.getCurrentInstance(), "someJSMethodToSetFocus('someForm:"+tabId+"');");

Index out of bound exception is raised because the panel has not been populated & fetching children from it. Giving value directly as <ice:panelTabSet value="#{viewBatchBean.batch.batchConfigurationTabList}"/> populates when the the page is rendered accordingly. So manually populating the panelTabSetRef.

In newer IceFaces version, tabIndex attribute has been added to panelTabSet.
