能否重写PXHidden类？重写StatementCreateBO函数报错求助

报错信息如下：

错误根源 #

重写ProcessCycles方法时，错误地将委托参数指定为RegenerateLastStatementDelegate，而非对应方法的ProcessCyclesDelegate，导致方法签名不匹配，触发报错。

修正后的完整代码 #

using PX.Data;

namespace PX.Objects.AR
{
    // Acuminator disable once PX1016 ExtensionDoesNotDeclareIsActiveMethod extension should be constantly active
    public class StatementCreateBO_Extension : PXGraphExtension<PX.Objects.AR.StatementCreateBO>
    {
        #region Event Handlers
        public delegate void RegenerateLastStatementDelegate(StatementCycleProcessBO graph, ARStatementCycle aCycle);
        [PXOverride]
        public virtual void RegenerateLastStatement(StatementCycleProcessBO graph, ARStatementCycle aCycle, RegenerateLastStatementDelegate baseMethod)
        {
            baseMethod(graph, aCycle);
        }

        public delegate void ProcessCyclesDelegate(StatementCycleProcessBO graph, ARStatementCycle aCycle);
        [PXOverride]
        public virtual void ProcessCycles(StatementCycleProcessBO graph, ARStatementCycle aCycle, ProcessCyclesDelegate baseMethod)
        {
            baseMethod(graph, aCycle);
        }
        #endregion
    }
}  

核心修正点 #

• 将ProcessCycles方法的第三个参数类型从RegenerateLastStatementDelegate替换为ProcessCyclesDelegate，确保委托类型与当前重写的方法完全对应，匹配Acumatica的方法重写签名要求。
