Description George Cook 2015-04-29 18:39:36 UTC
I have a custom generic content page base class:

		public class BasePage<TViewModel> : ContentPage where TViewModel : BaseViewModel

in my subclass I have the code behind :

			public partial class EventsPage : TwinEvents.Core.App.View.BasePage<EventsPageVM>

In the xaml I have:

		<BasePage 
	xmlns="http://xamarin.com/schemas/2014/forms" 
	xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" 
	x:Class="TwinEvents.Core.Events.View.EventsPage"
	x:TypeArguments="TwinEvents.Core.Events.View.EventsPageVM"
	Title="{Binding Title}"
	>

the issue I have is that the generated file won't compile, as it doesn't correctly refernece the BasePage class. It generates this:

		public partial class EventsPage : BasePage<TwinEvents.Core.Events.View.EventsPageVM>

instead of this:

		public partial class EventsPage : TwinEvents.Core.App.View.BasePage<TwinEvents.Core.Events.View.EventsPageVM>

I can temporarily fix it by adding the missing path qualifier; but then have to edit it *every time I change the file!*.

My question is.. is this a bug? is this expected behaviour? am I doing something wrong?

I mentioned this iin another thread; but realized that was a different problem, hence putting this here instead.

I'm working around it right now with a bash script that executes whenever I
build, and fixes the import statement; but it kind of sucks, especially seeing
as the only way I can get Xamarin to run it, is in an external window, so I
need to close a terminal window on each build... hmmph

resolved it - by using  a custom namespace. 

<page:BasePage 
    xmlns="http://xamarin.com/schemas/2014/forms" 
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" 
    xmlns:page="clr-namespace:TwinEvents.Core.App.View ; assembly=TwinEvents" 
    x:Class="TwinEvents.Core.Events.View.EventsPage"
    x:TypeArguments="TwinEvents.Core.Events.View.EventsPageVM"
    Title="{Binding Title}"
    >

please ignore this issue - perhaps it might help others if they find the ticket
though :)
