I thought you might be interested. I just posted more documentation on the FrameworkBootstrapper and how to customize it.

Siyfion,
Yes, the documentation is early stage. That's one reason Cocktail hasn't hit v1 yet. The short answer is yes, you have to jump through all these hoops, because you didn't extend from FrameworkBootstrapper. My bad, I didn't notice that part.
 
FrameworkBootstrapper does all the additional work that the Caliburn Bootstrapper doesn't do out of the box. It creates the container, makes sure things like the WindowManager, EventAggregator etc. get into the container and it configures all the DevForce hooks so that it all works together.
 
To answer your questions. No, you don't need to manually call Connect, provided you don't use a ConnectionOptions object that has ShouldConnect set to false. You also don't need to manually assign the AuthenticationContext. Once you extend from the FrameworkBootstrapper, everything bootstrapps automatically and Cocktail makes sure that the EntityManagers are configured and authenticated. This is the value add of Cocktail and it starts with the FrameworkBootstrapper.
 
I hear you on the tutorial front. Happy Hour is going to have more lessons that ease you into Cocktail. TempHire is the end product where an experienced Cocktail developer might land and yes, it also needs documentation. It's all a matter of limited time and resources unfortunately, but we'll get there.

Ok, I'll discuss the points you raised one at a time to keep things simple:

First of all, you are the second person I'm aware of, who decides to override the Configure method and completely neglects to call the base method. Such a thing normally only works if the base method has an empty body! In this case, the base Configure method contains the guts of the configuration, which you simply skipped. It should be pretty obvious that things won't work.

True, I wasn't calling the base.Configure() method and I should have been. However, it didn't make any difference as the Bootstrapper.Configure() method is empty, and my AppBootstrapper inherited directly from Bootstrapper not Cocktails' FrameworkBootstrapper.

The reason for this is simple, the documentation on the FrameworkBootstrapper<T> located here: http://drc.ideablade.com/xwiki/bin/view/Documentation/cocktail-application-bootstrapper doesn't provide any clue as to the functionality is provides over and above the default CaliburnMicro Bootstrapper class.

Second, you then proceed with creating your own CompositionContainer. Again, you are the second person doing this. Where is this coming from? Please help me understand why you thought you had to create your own CompositionContainer. I want to fix whatever got you down this road. Have you studied TempHire? Did you see it create it's own container anywhere?

As per my previous comment, not knowing what FrameworkBootstrapper provides that Bootstrapper does not, I followed through the CaliburnMicro documentation, leading me here: http://caliburnmicro.codeplex.com/wikipage?title=Customizing%20The%20Bootstrapper&referringTitle=Documentation Which goes over the basic MEF composition, producing very similar code to what I had.

Third, I see this too often unfortunatley. The kind of logic you are performing in the ShellViewModel constructor, does not belong in a constructor. A construtor is not a method that gets called on a completely constructed object. It gets called DURING the construction. It's not safe to do this kind of logic in the middle of construction. It just isn't.

Again, in one of my previous posts I stated that I moved some stuff into the constructor of the ShellViewModel so that it was easier to debug, what with it being all in one place. Indeed, afterwards it will go into the OnInitialize() method.


Doing it this way, I had to manually do the following:

protected override void OnInitialize()
        {
            var entityManagerProvider = IoC.Get<IEntityManagerProvider<LabelLogicEntities>>();
            entityManagerProvider.Manager.Connect();

            var loginCredential = new LoginCredential("Dev", null, null);
            _authenticationService.Login(loginCredential);

    // ********** NOTE THIS LINE  ************* //
            entityManagerProvider.Manager.AuthenticationContext = _authenticationService.AuthenticationContext;

            ShowSheetCreation();

            base.OnInitialize();
        }

I'm assuming if I switch to using the FrameworkBootstrapper I can get rid of some of this code? ie. Do I need to manually call Connect()? Do I need to manually assign the _authenticationService.AuthenticationContext to the Manager.AuthenticationContext?

The main reason I feel that I have fallen into these issues is due to the lack of proper documentation regarding the classes discussed, and very little documentation on the TempHire project.

Also, one could argue that the HappyHour Tutorial is a brilliant step-by-step guide, however it's very simplistic and focuses much more on CaliburnMicro than "Cocktail" per se. The TempHire goes the other way.... Too complex and hardly any documentation to go through it.

Perhaps another "middle ground" tutorial would be a good addition? Especially one that goes over the Cocktail concepts explicitly, rather than CaliburnMicro (like HappyHour). A simple solution that uses Repositories, EntityManagerProviders, etc.

I stopped reading at this post. A number of issues here.
First of all, you are the second person I'm aware of, who decides to override the Configure method and completely neglects to call the base method. Such a thing normally only works if the base method has an empty body! In this case, the base Configure method contains the guts of the configuration, which you simply skipped. It should be pretty obvious that things won't work.

Please help me understand why you thought you had to create your own CompositionContainer. I want to fix whatever got you down this road. Have you studied TempHire? Did you see it create it's own container anywhere? 
 
All you need from your Configure method are the following two lines and they belong in PrepareCompositionContainer. DON'T FORGET TO CALL base.PrepareCompositionContainer when you override the method. Also, you don't need .With(ConnectionOptions.Default.Name). That's redundant. If you don't specify anything it automatically uses the default. That's what a default is usually for.
 
batch.AddExportedValue<IEntityManagerProvider<LabelLogicEntities>>(new EntityManagerProvider<LabelLogicEntities>())
batch.AddExportedValue<IAuthenticationService>(new AuthenticationService());
 
Third, I see this too often unfortunatley. The kind of logic you are performing in the ShellViewModel constructor, does not belong in a constructor. A construtor is not a method that gets called on a completely constructed object. It gets called DURING the construction. It's not safe to do this kind of logic in the middle of construction. It just isn't.
 
This stuff belongs into the OnInitialize method that you inherit from Conductor<IScreen>. Override OnInitialize and perform any initialization that involves querying the database etc. It gets called once when the ViewModel is first activated.
 
I think that's enough to fix for now.
 
Originally posted by Siyfion

It was crashing in another place, but to try it out I moved some code into my ShellViewModel constructor, so it now looks like this:

    [Export(typeof(IShell))]
    class ShellViewModel : Conductor<IScreen>, IShell
    {
        private readonly IAuthenticationService _authenticationService;

        [ImportingConstructor]
        public ShellViewModel(IAuthenticationService authenticationService)
        {
            _authenticationService = authenticationService;

            var loginCredential = new LoginCredential("Dev", null, null);
            _authenticationService.Login(loginCredential);

            var userRepository = IoC.Get<IUserRepository>();
            var owner = userRepository.CreateOwner();
            var saveResult = userRepository.SaveSync();

            ShowSheetCreation();
        }

        public void ShowSheetCreation()
        {
            var sheetCreation = IoC.Get<ISheetCreation>();
            ActivateItem(sheetCreation);
        }

        private string _title;
        public string Title
        {
            get { return _title; }
            set
            {
                if (_title == value) return;
                _title = value;
                NotifyOfPropertyChange(() => Title);
            }
        }

        public void SetTitle(string title)
        {
            if (!string.IsNullOrEmpty(title))
                Title = title;
        }
    }

And my AppBootstrapper:

        protected override void Configure()
        {
            _container =
                new CompositionContainer(
                    new AggregateCatalog(
                        AssemblySource.Instance.Select(x => new AssemblyCatalog(x)).OfType<ComposablePartCatalog>()));

            var batch = new CompositionBatch();
            batch.AddExportedValue<IWindowManager>(new WindowManager());
            batch.AddExportedValue<IEventAggregator>(new EventAggregator());
            batch.AddExportedValue<IEntityManagerProvider<LabelLogicEntities>>(
                new EntityManagerProvider<LabelLogicEntities>().With(ConnectionOptions.Default.Name));
            batch.AddExportedValue<IAuthenticationService>(
                new AuthenticationService().With(ConnectionOptions.Default.Name));
            batch.AddExportedValue(_container);

            _container.Compose(batch);

            Application.ShutdownMode = ShutdownMode.OnExplicitShutdown;
        }

I've changed my constructor to the following, but I'm still getting an exception thrown, when I try to perform either a Save() or a SaveAsync() on the user repository, which internally just call Manager.SaveChanges() or Manager.SaveChangesAsync(). 

        [ImportingConstructor]
        public ShellViewModel(IAuthenticationService authenticationService)
        {
            _authenticationService = authenticationService;

            var loginCredential = new LoginCredential("Dev", null, null);
            _authenticationService.Login(loginCredential);

            var entityManagerProvider = IoC.Get<IEntityManagerProvider<LabelLogicEntities>>();
            entityManagerProvider.Manager.Connect();

            var userRepository = IoC.Get<IUserRepository>();
            var owner = userRepository.CreateOwner();
            var saveResult = userRepository.SaveAsync(OnSuccess, OnFail);

            ShowSheetCreation();
        }

        private void OnFail(Exception exception)
        {
            throw exception;
        }

        private void OnSuccess()
        {
            throw new NotImplementedException();
        }

The OnFail throws the following:

Unable to login: Object reference not set to an instance of an object.

Ok, yet again I've got it a step closer, however now I've got the error:

1) Call Connect() before doing a Login.

So I'm guessing that I manually need to call Connect() on the EntityManagerProvider.Manager?

It was crashing in another place, but to try it out I moved some code into my ShellViewModel constructor, so it now looks like this:

    [Export(typeof(IShell))]
    class ShellViewModel : Conductor<IScreen>, IShell
    {
        private readonly IAuthenticationService _authenticationService;

        [ImportingConstructor]
        public ShellViewModel(IAuthenticationService authenticationService)
        {
            _authenticationService = authenticationService;

            var loginCredential = new LoginCredential("Dev", null, null);
            _authenticationService.Login(loginCredential);

            var userRepository = IoC.Get<IUserRepository>();
            var owner = userRepository.CreateOwner();
            var saveResult = userRepository.SaveSync();

            ShowSheetCreation();
        }

        public void ShowSheetCreation()
        {
            var sheetCreation = IoC.Get<ISheetCreation>();
            ActivateItem(sheetCreation);
        }

        private string _title;
        public string Title
        {
            get { return _title; }
            set
            {
                if (_title == value) return;
                _title = value;
                NotifyOfPropertyChange(() => Title);
            }
        }

        public void SetTitle(string title)
        {
            if (!string.IsNullOrEmpty(title))
                Title = title;
        }
    }

And my AppBootstrapper:

        protected override void Configure()
        {
            _container =
                new CompositionContainer(
                    new AggregateCatalog(
                        AssemblySource.Instance.Select(x => new AssemblyCatalog(x)).OfType<ComposablePartCatalog>()));

            var batch = new CompositionBatch();
            batch.AddExportedValue<IWindowManager>(new WindowManager());
            batch.AddExportedValue<IEventAggregator>(new EventAggregator());
            batch.AddExportedValue<IEntityManagerProvider<LabelLogicEntities>>(
                new EntityManagerProvider<LabelLogicEntities>().With(ConnectionOptions.Default.Name));
            batch.AddExportedValue<IAuthenticationService>(
                new AuthenticationService().With(ConnectionOptions.Default.Name));
            batch.AddExportedValue(_container);

            _container.Compose(batch);

            Application.ShutdownMode = ShutdownMode.OnExplicitShutdown;
        }

You are doing something in the ShellViewModel constructor that blows up, so the instance creation fails. Why it would create an instance of the ShellViewModel, though, when you try to save is confusing me. Given the name I assume this is your main ViewModel. If that's so it would get created before you run your first query.
 
I sense there's something upside down. From where did you run the query etc. How do you login (see my previous post)?

Perhaps I'm getting a bit confused; is the name I am specifying the name of the class, or the name contained within the returned ConnectionOptions?

If it's the name of the class, I've tried that and put a breakpoint in GetConnectionOptions, but it never seemed to be hit, at what point would it call this?

You use it by specifiying the name of the ConnectionOptions you want your EntityManagerProvider to use through the "With" method. Note that the With method clones the EMP and configures the clone with the new ConnectionOptions. If you use a single shared EntityManagerProvider, I assume you are currently instantiating it in the PrepareCompositionContainer method in your bootstrapper and add it to the CompositionBatch. In that case, you would do the following:
 
        protected override void PrepareCompositionContainer(CompositionBatch batch)        {            base.PrepareCompositionContainer(batch);             batch.AddExportedValue<IEntityManagerProvider<yourentitymanagertype>>(                new EntityManagerProvider<yourentitymanagertype>().With("yourconnectionoptionname"));        }

This may sound silly, but after creating a custom implementation of IConnectionOptionsResolver, how do I actually use it!? In particular, if I am using a single shared EntityManagerProvider throughout the application?]]> Thu, 22 Mar 2012 06:12:57 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3352&PID=13057#13057
