Setting default tab

Hi,

I have a problem, I am working on tabs template and created a side menu and a page that has a list of actions which opens a tabs page. I can not set which tab is the active tab so the initial screen comes up as blank but clicking on the tab works.

This is how the code looks. What can i change to make this work?

import {IonicApp, Page, NavController, NavParams} from 'ionic/ionic';

@Page({
  templateUrl: 'app/addresses/delivery-address.html'
})
class TabsDeliveryAddressPage {
  constructor() {
  }
}

@Page({
  templateUrl: 'app/addresses/billing-address.html'
})
class TabsBillingAddressPage {
  constructor() {
  }
}

@Page({
  templateUrl: 'app/addresses/addresses.html'
})
export class AddressesPage {
  constructor(app: IonicApp, nav: NavController, navParams: NavParams) {
    this.nav = nav;
    
    this.selectedItem = navParams.get('item');
    
    this.tab1 = TabsBillingAddressPage;
    this.tab2 = TabsDeliveryAddressPage;
    
    this.rootPage = TabsBillingAddressPage;
  }
}

Add another blank page in your tabs and set as the default, and hide that option.
