从6.10或2017R2升级到2018R1后，CROpportunity上的自定义字段不会显示已保存的值

问题描述

我在我的定制项目中对CROpportunity进行了DAC扩展，该扩展在6.10和2017R2中运行良好。现在，我已将网站升级到2018R1，并且自定义字段不再起作用。保存记录后，即使数据库正确保存了值，自定义字段也将变为空白。

I made a DAC extension on CROpportunity in my customization project which was working well in 6.10 and 2017R2. Now I upgraded my site to 2018R1 and my custom fields don't work anymore. As soon as I save my record, the customized field goes blank even if the database saved the value correctly.

为什么会这样？

推荐答案

在版本2018R1中， PX.Objects.CR.CROpportunity 成为 PX.Objects.CR.Standalone.CROpportunity 。

In version 2018R1, PX.Objects.CR.CROpportunity became a projection of PX.Objects.CR.Standalone.CROpportunity.

为了使投影正确获取其自定义字段值，您还需要自定义独立DAC，并将 PX.Objects.CR.CROpportunity 的BQL字段设置为 PX.Objects.CR.Standalone.CROpportunity 。

In order for the projection to get its customized fields values correctly, you need to also customize the Standalone DAC and set the BQL Field of PX.Objects.CR.CROpportunity point to PX.Objects.CR.Standalone.CROpportunity.

这里是一个示例：

Here is an example :

public class CROpportunityExt : PXCacheExtension<PX.Objects.CR.CROpportunity> 
{
    #region UsrTest
    [PXDBDecimal(BqlField = typeof(CROpportunityStandaloneExt.usrTest))]
    [PXUIField(DisplayName="Test Field")]

    public virtual Decimal? UsrTest { get; set; }
    public abstract class usrTest : IBqlField { }
    #endregion
}

public class CROpportunityStandaloneExt : PXCacheExtension<PX.Objects.CR.Standalone.CROpportunity>
{
    #region UsrTest
    [PXDBDecimal]
    [PXUIField(DisplayName="Test Field")]

    public virtual Decimal? UsrTest { get; set; }
    public abstract class usrTest : IBqlField { }
    #endregion
}
