Question

有没有人使用过MvxAutoCompleteTextView？在选择建议的项目时，它会以下面的堆栈跟踪结束：

Droid项目：配置MvxAutoCompleteTextView的xaml文件是：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:local="http://schemas.android.com/apk/res/pocketseller.droid"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <MvxAutoCompleteTextView
        android:id="@+id/selectionarticlesearchbox"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        local:MvxItemTemplate="@layout/selectionarticleitem"
        local:MvxBind="Text SearchKey, Mode=TwoWay; ItemsSource ListAddresses; PartialText LabelTitle; SelectedObject Address" />
</LinearLayout>

核心项目ViewModel：Binded SearchKey

private string _searchKey;
public string SearchKey { get { return _searchKey; } set { _searchKey = value; RaisePropertyChanged(() => SearchKey); SearchNow(); } }

核心项目ViewModel：Binded ListAddresses是：

private List<Adress> _listAddresses;
public List<Adress> ListAddresses { get { return _listAddresses; } set { _listAddresses = value; RaisePropertyChanged(() => ListAddresses); } }

Core Project ViewModel：分配给Address属性的选定对象：

public Adress Address
{
    get { return DocumentService.Document.Adress; }
    set
    {
        RaisePropertyChanged(() => Address);
        DocumentService.Document.Adress = value;
        Messenger.Publish(new DocumentMessage(this, EDocumentAction.ShowDocumentOrder));
    }
}

希望我的问题是可以理解的，如果不是，请留下一个问题，我会尽力完成这个问题，谢谢！

P.S。这闻起来似乎是一个错误似乎MvxAdapter中的_itemsSource没有正确填充（？）
