Please fill out either the bug or feature request section and remove whatever section you are not using.

Bug

• Version Number of Control: 1.2.1 and olders
• Device Tested On:
• Simulator Tested On: Simulator

Affects

• [x ] iOS
• Android

Expected Behavior

When the order is over, pop to root.

Actual Behavior

When the order is over nothing happens, no error is reported on console, but the app remains on the same view.

Steps to reproduce the Behavior

After login, the first page is the MainPage, then you first select Pedidos de Vendas (Orders), fill the CNPJ field with a CNPJ register previously registered and all the form will be filled (e.g. 07092892000147), you fill the field Adiciona Produto (Add Product, which uses combobox and entry from xfxcontrols), on the next Page you fill the field Qtde (it its how many products you want to buy), choose which unity of measurement you want to use. Now you can click on button Adicionar(Add) and on the previous page on Finalizar (Fish the order).
On the next page you can fill the last two field with random values and the click on button Finalizar again (finish).

Feature Request:

I don't why, but after I've added XfxControls, only on iOS version, this problem happens without give any message. But I realize that the stack isn't empty to return to the root view (MainPage).

The issue is that this worked some time in the past when another developer worked in this project, but I'm new with Xamarin so I don't why this happens now.
