  public void onEventSelect(ScheduleEntrySelectEvent selectEvent){

    // what should I need to do here to set "Tab 2" if click on any event.


    }

Answer 1

First, you need to set the activeIndex attribute of your <p:tabView>, like this: <p:tabView activeIndex="#{bean.selectedTab}">. It's an Integer.

Second, in your bean method, whenever you want to change the active tab, set selectedTab to the tab you want to be selected.

Third, remember to update the <p:tabView>.

You could also do that using JavaScript. Just set the widgetVar attribute of your <p:tabView>, like this: <p:tabView widgetVar="myTabView">.

Then use the JavaScript function myTabView.select(tabIndex), where tabIndex is the index of the tab you want to select.

You can do that at any javascript event, for example: <p:commandButton oncomplete="myTabView.select(1)" /> would select the second tab after the action of the commandButton completed.

Make sure you read PrimeFaces docs.

1. You can use binding property in a tag p:tabView.

<p:tabView id="tabGeneral" binding="#{Bean.tabView}" dynamic="true">

2. Create Tabview Object in your Bean.

private TabView tabView;

public TabView getTabView() {
  return tabView;
}

public void setTabView(TabView tabView) {
  this.tabView = tabView;
}

3. Set int like a index in your tabview.

tabView.setActiveIndex(0);

4. Update tabView.

RequestContext.getCurrentInstance().update("tabGeneral");
