      	self.navCtrl.getPrevious().data.selectedCategoryId  = self.selectedCategoryKeyId;

That is unmaintainable spaghetti. Use mutually injected service providers or NavParams for exchanging data amongst pages instead.

That is so funny.

As rapropos said: There a 2 common ways passing data to a page. As NavParams or with a provider.

Imho, if you want collect data from different pages, that should be used from an other page, it personnally will prefer a shared provider. In a life cycle hook you canb update your page.

use “ionViewDidEnter” instead “ionViewWillEnter”

sir same result ionViewDidEnter not trigger after pop?

ionViewDidEnter run anytime you enter a page.
If its not work for you, you may doing something wrong

Worrying about which lifecycle event to use with this disastrous design is simply rearranging deck chairs on the Titanic. Write a service provider already.
