Acumatica - 试图复制TYPE字段的逻辑

Question

我试图复制acumatica的类型（字段）的逻辑。我想在更改类型时重置所有字段，我不知道我是否错过了aspx中的任何配置但是它给了我这个错误＆＃34;错误：在字段处理期间发生错误参考Nbr 。：错误：＆＃39;参考Nbr。＆＃39;在系统中找不到。＆＃34;

这是我的代码：

DAC：

#region Type
    public abstract class type : PX.Data.IBqlField
    {
    }
    protected string _Type;
    [PXDBString(15, IsKey = true, IsFixed = true)]
    [PXDefault("Termination")]
    [PXUIField(DisplayName = "Type")]
    [PXStringList(
        new string[] { "Termination", "Repossession", "Pretermination" },
        new string[] { "Termination", "Repossession", "Pretermination" })]
    public virtual string Type

        get
