下面是我的sysOperation framework类，我的问题是，当我打开对话框并按OK时，什么都没有发生，这段代码怎么了？

类别：

[DataContractAttribute]
class ProdutionFLowsContract implements SysOperationInitializable,SysOperationValidatable
{
    ProductionFlowId idOfCopy;
    int copyToDo;

   
    public void initialize()
    {
        idOfCopy = "";
        copyToDo = 0;
    }
    [DataMemberAttribute("idOfCopy"),SysOperationLabelAttribute(literalStr("TODO(Id)")),SysOperationDisplayOrderAttribute("1")]

    [DataMemberAttribute("copyToDo"),SysOperationLabelAttribute(literalStr("copyToDo(Copy)")),SysOperationDisplayOrderAttribute("2")]
    public int parmCopyToDo(int     _copyToDo = copyToDo)
    {
        copyToDo = _copyToDo;

        return copyToDo;
    }

    public boolean validate()
    {
        
        return false;
    }

}

您的合同验证总是失败，因为它总是返回

false

，并且在信息日志中不显示任何错误：

public boolean validate()
{
    return false;
}

尝试将

return false

替换为

return true

或删除

sysoperationvalidable

和

validate
