Question

In a sencha touch 2 Ext.navigation.View, it is possible to push() and pop() other views in and out. Those other views fire events like hide and show.Sadly, those events are fired in this order when pushing: (note the bold ones)

1. initialize
2. hide
3. activate
4. show

and like this when popping:

1. deactivate
2. hide
3. show
4. remove
5. destroy

So relying on either show or hide event is not the best idea as both get fired in both situations.
I consider this a bug and something similar has already been discussed. Nevertheless this behaviour is still present in the version I use (ST 2.0.1.1) and according to the explanation of @rdougan in the forum:

The reason behind this is that when an item is removed from a card
layout, it may actually be shown somewhere else – or perhaps it is
changing to be floatable. So we must revert the item back to its
original visible state.

it won’t be changed as well. So I was trying to find out which event is really happening.

There is a solution for this problem. Assuming one listens to the event inside the view, not a controller, you may use this litte snippet:

Ext.Array.contains(this.up('navigationview').getActiveItem().getXTypes().split('/'), this.xtype)

to check whether your view is actually shown (true) or hidden (false). Of course, you have to define your own xtype config property on the views you are using to make that work. In my case, it is an Ext.Panel.
