Custom field on CROpportunity doesn't display saved value since upgrading from 6.10 or 2017R2 to 2018R1

Question

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.

Why is this happening ?

Answer 1

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

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
}
