Acumatica PXUIFieldAttribute SetError给出错误

Question

我正在尝试验证输入到Support Split表中的值，为什么我无法抓住ItemExtension？

protected void atcProjectCostCenterTable_CostCenterSplit_FieldVerifying(PXCache cache, PXFieldVerifyingEventArgs e, PXFieldVerifying InvokeBaseHandler)
{
    if (InvokeBaseHandler != null)
        InvokeBaseHandler(cache, e);
    var row = (atcProjectCostCenterTable)e.Row;

    if (row.ContractID > 0)
    {
        decimal? hun = 100;
        PX.Objects.CT.ContractExt item = row.GetExtension<PX.Objects.CT.ContractExt>();

        if (CostCenterSplit.Select().Count >= 1)
        {
            if (item.UsrCostCenterSum.Value != hun)
            {
                PXUIFieldAttribute.SetError<atcProjectCostCenterTable.costCenterSplit>(cache, row, "Support Percentages must equal 100%");
                //throw new PXSetPropertyException("Cost Center Percentages must equal 100%", PXErrorLevel.Warning);
            }
        }
    }
}

Answer 1

尼克，请更换

PX.Objects.CT.ContractExt item = row.GetExtension<PX.Objects.CT.ContractExt>();

带

PX.Objects.CT.ContractExt item = Base.Project.Current.GetExtension<PX.Objects.CT.ContractExt>();

或

PX.Objects.CT.ContractExt item = Base.Project.Cache.GetExtension<PX.Objects.CT.ContractExt>(Base.Project.Current);

您当前的代码无法使用，因为ContractExt扩展了Contract DAC，而不是atcProjectCostCenterTable。由于PMProject继承自Contract，因此为Contract DAC定义的DAC扩展也可用于PMProject实例。

Answer 2

  Contract con = Base.Project.Current;
  PX.Objects.CT.ContractExt item = con.GetExtension<PX.Objects.CT.ContractExt>();
