Hi Jimmy,

Sorry for your inconvenience, could you copy paste your output (the one that have UNHANDLED EXCEPTION)

From what i see there are a few possibility for cause of this error possibly in your form view model (caused by different value type between FormMetaData and Parameter inside Model on that view model).

Also looks like your code work in our end.

Description

Error is being encountered when using SelectionInput with Android, which is not being experienced on iOS using the same ListViewModels.

Step to Reproduce

Use a selection with deep navigation properties.

[Editor(EditorType.Selection)]
[SelectedItemBinding(Path = "Machine.Class")][SelectionInput(SelectionMode.Single, DisplayMemberPath = "ClassName", ListSourceType = typeof(ClassListViewModel))]
[Binding(Path = "Machine.Class.ClassName")]
public static Class Class;

And here's the ListViewModelBase... we decided to use ListViewModelBase because USING DataListViewModelBase creates more issues with this scenario.

    public class ClassListViewModel
        : ListViewModelBase<Class>
    {
        #region Field Variables

        private IQueryDefinition f_ViewQueryDefinition;

        #endregion

        #region Properties

        /// <summary>
        /// Gets the repository.
        /// </summary>
        /// <value>The repository.</value>
        public IClassRepository Repository
        {
            get
            {
                return Container.Current.CanResolve<IClassRepository>() ? 
                    Container.Current.Resolve<IClassRepository>() : 
                    new ClassRepository(null);
            }
        }

        /// <summary>
        /// Gets the view query.
        /// </summary>
        /// <value>The view query.</value>
        public IQueryDefinition ViewQuery
        {
            get
            {
                if (this.f_ViewQueryDefinition == null)
                    this.f_ViewQueryDefinition = new ClassQueryDefinition();

                return this.f_ViewQueryDefinition;
            }
        }

        /// <summary>
        /// Initializes the select parameter used when loading data.
        /// </summary>
        /// <returns>The select parameter.</returns>
        /// <param name="queryDescriptor">Query descriptor.</param>
        protected virtual SelectParameter InitializeSelectParameter(QueryDescriptor queryDescriptor)
        {
            var parameter = new SelectParameter(queryDescriptor);

            return parameter;
        }

        #endregion

        #region Methods

        public async override void Navigated(NavigatedParameter parameter)
        {
            this.ActivityPresenter.Show("Loading...", ActivityStyle.SmallIndicatorWithText, true);

            var p_SourceItems = await this.Repository.GetAllAsync(this.InitializeSelectParameter(this.ViewQuery.GetQueryDescriptor()));

            this.Items = p_SourceItems.Items.OrderBy(p => p.ClassName);

            this.ActivityPresenter.Hide();

            base.Navigated(parameter);
        }

        #endregion
    }
