缺少成员名( xaf CriteriaOperator)

Question

设置“视图集合源”时会出现以下错误

我的简化代码我们

public partial class FilterProductListViewController : ObjectViewController<ListView, .Product>
{
    public FilterProductListViewController()
    {
    }
    protected override void OnActivated()
    {
        base.OnActivated();
        CriteriaOperator op = CriteriaOperator.Parse("[WeBuyThis]")
        View.CollectionSource.Criteria["FilterProduct"] = op;  // errors here
    }
}

DevExpress.Data.Linq.Helpers.CriteriaToExpressionConverterInternal.MakePropertyAccess(Expression表达式: System.MissingMemberException HResult=0x8013151A Message=MissingMember_Name Source=DevExpress.Data.v21.2 StackTrace(字符串( DevExpress.Data.Linq.CriteriaToEFExpressionConverter.Convert(ParameterExpression thisExpression )，( DevExpress.Data.Linq.Helpers.CriteriaToQueryableExtender.AppendWhere(IQueryable src，ICriteriaToExpressionConverter转换器，CriteriaOperator op)在DevExpress.ExpressApp.EFCore.EFCoreObjectSpace.GetObjectsQuery(CriteriaOperator标准下，op‘1排序，( DevExpress.ExpressApp.EFCore.EFCoreCollection.Init() at DevExpress.ExpressApp.EFCore.EFCoreCollection.get_InnerList() at DevExpress.ExpressApp.EFCore.EFCoreCollection.get_Count() at DevExpress.ExpressApp.ProxyCollection.get_Count() at at System.Windows.Forms.CurrencyManager.SetDataSource(Object dataSource( at System.Windows.Forms.CurrencyManager..ctor(Object dataSource) at System.Windows.Forms.BindingContext.EnsureListManager(Object dataSource，String dataMember) at System.Windows.Forms.BindingContext.get_Item(Object dataSource，( DevExpress.Data.Platform.Compatibility.DefaultDesktop.DevExpress.Data.Platform.Compatibility.IDesktopBridge.GetListFromBindingContext(Object上下文中的String dataMember)，DevExpress.Data.Helpers.MasterDetailHelper.GetDataSourceCore(Object上下文中的Object dataSource，String dataMember)，DevExpress.Data.Helpers.MasterDetailHelper.GetDataSource(Object上下文中的Object dataSource，String dataMember，IList existingListSource)，对象dataSource，String dataMember)

原因是当我拼错了属性名时

例如，如果产品没有WeBuyThis属性
