I’m getting a build error in the UpdateExpirationDate() function:

    public class KBCCProcessingCenterMaintExt : PXGraphExtension<CCProcessingCenterMaint>
    {
        [PXOverride]
        public PXAction<CCProcessingCenter> updateExpirationDate;

        public static bool IsActive() => PXAccess.FeatureInstalled<PX.Objects.CS.FeaturesSet.integratedCardProcessing>();

        [PXUIField(DisplayName = "Update Expiration Dates", MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select)]
        [PXButton]
        public virtual IEnumerable UpdateExpirationDate(PXAdapter adapter)
        {
            if (Base.ProcessingCenter.Current != null && Base.ProcessingCenter.Current.ProcessingTypeName == typeof(KBTokenizedProcessing).FullName)
            {
                throw new PXException(KBMessages.FeatNotSupported);
            }

            return Base.UpdateExpirationDate(adapter);
        }

The error is: 'CCProcessingCenterMaint' does not contain a definition for 'UpdateExpirationDate' and no accessible extension method 'UpdateExpirationDate' accepting a first argument of type 'CCProcessingCenterMaint' could be found (are you missing a using directive or an assembly reference?)

I looked in release notes here but I couldn’t find anything regarding this change to PX.Objects:

Has anyone come across this issue or can someone point me in the right direction

    ​@bpgraves  I have not checked this, but can you please try this and verify.

    [PXOverride]
    public virtual IEnumerable UpdateExpirationDate(
        PXAdapter adapter, 
        Func<PXAdapter, IEnumerable> baseMethod)
    {
        if (Base.ProcessingCenter.Current != null && 
            Base.ProcessingCenter.Current.ProcessingTypeName == 
            typeof(KBTokenizedProcessing).FullName)
        {
            throw new PXException(KBMessages.FeatNotSupported);
        }
        return baseMethod(adapter);   
    }

          }
          return baseMethod(adapter);   
      }

       

      It builds but I don’t understand why the [PXOverride] is necessary since it doesn’t override anything.  It’s a function triggered by a button (see above).

      ​@bpgraves 

       

      This could be because you were overriding the PXAction rather than the method itself.

      You should always give the method the PXOverride attribute.

        If the UpdateExpirationDate method was removed in 26R1, then how can the user update the expiration date now?

        This override method requires a basemethod as a new parameter.  Since the Base method for this function no longer exists in 26R1 (or 25R1), it is not clear what needs to be passed as the 3rd parameter.
