发布事务信息类型不匹配错误

Question

使用Tridion2009，SP1，因此使用旧的COM+ TOM API。我试图获取PublishTransaction的信息，但每次调用PublishTransaction.Information属性时都会得到一个错误。

下面是我的代码：

try
{
    var pubTrans = (PublishTransaction)tdse.GetObject("tcm:0-166535-66560",
                                                      EnumOpenMode.OpenModeView);
    Console.WriteLine("transaction id=" + pubTrans.ID);
    Console.WriteLine("transaction itemtype=" + pubTrans.itemType.ToString());
    Console.WriteLine("transaction info=" + pubTrans.Information);
}
catch (Exception e)
{
    Console.WriteLine(e.Message, e.StackTrace);
}

上面的交易ID和项目类型打印正常。我还有其他代码可以很好地使用Delete方法，但每当我尝试获取信息时，它都会崩溃。

下面是错误：

<tcm:Error xmlns:tcm="http://www.tridion.com/ContentManager/5.0" ErrorCode="D"
           Category="18" Source="Kernel" Severity="1">
  <tcm:Line Cause="false" MessageID="16138">
    <![CDATA[Unable to get Information of Unknown (tcm:0-166535-66560).]]>
    <tcm:Token>RESID_4485</tcm:Token><tcm:Token>Information</tcm:Token>
    <tcm:Token>RESID_4663</tcm:Token><tcm:Token>tcm:0-166535-66560</tcm:Token>
  </tcm:Line>
  <tcm:Line ErrorCode="D" Cause="true"><![CDATA[Type mismatch]]></tcm:Line>
  <tcm:Details>
    <tcm:CallStack>
      <tcm:Location>PublishTransaction.Information</tcm:Location>
      <tcm:Location>PublishTransaction.Information</tcm:Location>
    </tcm:CallStack>
  </tcm:Details>
</tcm:Error>

我搜索了SDL Tridion World论坛，但找不到答案。我是否缺少热修复程序，我是否应该联系支持人员，或者是否有其他方法可以获取交易信息？

Answer 1

我真的不确定(在晚上这个时候不深入挖掘)，但是“信息”属性实际上是一个XMLElement而不是文档中所说的字符串？使用调试器时，是否可以在此属性上放置监视以查看其包含的内容？

我尝试了另一种方法来获取PublishTransaction信息。以下是代码：

PublishTransaction pubTrans = (PublishTransaction)tdse.GetObject(
                                                    "tcm:0-4294103-66560",
                                                    EnumOpenMode.OpenModeView, 
                                                    null, 
                                                    XMLReadFilter.XMLReadNull);
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(pubTrans.GetXML(XMLReadFilter.XMLReadAll));
XmlNamespaceManager nameSpace = new XmlNamespaceManager(xmlDoc.NameTable);
nameSpace.AddNamespace("tcm", "http://www.tridion.com/ContentManager/5.0");
nameSpace.AddNamespace("xlink", "http://www.w3.org/1999/xlink");
Console.WriteLine("transaction id=" + pubTrans.ID); 
Console.WriteLine("transaction itemtype=" + pubTrans.itemType.ToString());
EnumPublishTransactionState transState = pubTrans.get_State();
if (transState == EnumPublishTransactionState.Failed)
  Console.WriteLine("transaction info=" + 
    xmlDoc.SelectSingleNode("/tcm:PublishTransaction/tcm:Data/tcm:Information",
    nameSpace).InnerText);

我没有一个工作环境，所以我只是查看我现有的任何可用的代码。这是来自事件系统的代码片段，仅当您拥有管理员权限时才会删除队列项目：

public void OnPublicationPublishPost(Publication publication, IXMLDOMDocument2 publishResult)
{
    TDSE tdse = Utilities.GetTDSEInstance();
    publishResult.setProperty("SelectionNamespaces", "xmlns:tcm=\"http://www.tridion.com/ContentManager/5.0\"");
    PublishTransaction publishTransaction = Utilities.GetTridionItem<PublishTransaction>(publishResult.selectSingleNode("/*/*").attributes[2].text, null) as PublishTransaction;
    User user = Utilities.GetTridionItem<User>(publishResult.selectSingleNode("/tcm:PublishResponse/tcm:PublisherRequest/tcm:User").attributes[0].text, null) as User;
    TDSPrivileges isAdmin = user.privileges;
    if (isAdmin != TDSPrivileges.TdsPrivilegeSystemAdministrator)
    {
        publishTransaction.Delete();
    }
}
