AS you can see I inlude the retail customer view in the retail state and the wholesale customer view in the wholesale state. The problem is that when I run my app they don't appear on neither state.
Any ideas?

This is an odd approach to me. The whole purpose of the ViewStack is to only show one item at once. This is a very odd approach.
I see you have a tabbar whose dataProvider is the ViewStack. However, your ViewStack is not created as a bindable property on the component, and you never seem to set up an initial state. So, I theorize that this is happening:
App Loads in default state, which is the empty string
ViewSTack and/or TabBar are initialized without those children
App state changes for some reason
TabBar does not update
CreationPolicy may come into play too, but I'm not sure. You'll have to step through the code to figure out what's going on. I would strongly recommend you consider an alternate approach to this. Possibly creating the tabbar navigator dataProvider manually based on user security settings or the current state.
