公平警告：此问题的设置很长，请耐心等待并留在我身边。

我的解决方案包中有两个功能。第一个是一组站点字段和内容类型;让我们称之为功能A 。其中包括“TaxonomyFieldType”类型的字段和“Note”类型的关联字段（an explanation of the note field）。

<Elements ...>  
<Field ID="{956a1078-ec35-4c04-83c4-0a3742119496}" 
        Name="TaxonomyTextField" 
        Type="Note" DisplayName="Tags_0" 
        ShowInViewForms="FALSE" 
        Required="FALSE"
        Group="MyGroup"
        Hidden="TRUE"/>

<Field ID="{92BC866B-0415-45F0-B431-D4DF69C421CC}"
        Name="Tags"
        DisplayName="Custom Tags"
        Type="TaxonomyFieldType"
        ShowField="Term1033"
        Required="FALSE"
        Group="MyGroup"
        >
  <Customization>
    <ArrayOfProperty>
      <Property>
        <Name>IsPathRendered</Name>
        <Value xmlns:q7="http://www.w3.org/2001/XMLSchema" p4:type="q7:boolean" xmlns:p4="http://www.w3.org/2001/XMLSchema-instance">true</Value>
      </Property>
      <Property>

      </Property>
    </ArrayOfProperty>
  </Customization>
</Field>
</Elements>

和

<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <!-- Parent ContentType: Item (0x01) -->
  <ContentType ID="0x0100b61c774f4c0e4a89bf230cbb44cd4f75"

               Description="Description of My Content Type"
               Inherits="FALSE"
               Overwrite="TRUE"
               Version="0">
    <FieldRefs>
      <FieldRef ID="{52578fc3-1f01-4f4d-b016-94ccbcf428cf}" DisplayName="Comments" Name="Comments" Required="FALSE"/>
      <FieldRef ID="{956a1078-ec35-4c04-83c4-0a3742119496}" Name="TimeTrackerTaxonomyTextField"/>
      <FieldRef ID="{92BC866B-0415-45F0-B431-D4DF69C421CC}" DisplayName="Tags" Name="Tags" Required="FALSE"/>
    </FieldRefs>
  </ContentType>
</Elements>

在第一个功能的功能接收器中（我们称之为功能A），我以编程方式检索此TaxonomyField和确保将其配置为从预定的术语集中检索术语：

public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
    SPWeb web = GetWebObj(properties.Feature.Parent);
    Guid fieldId = new Guid("92BC866B-0415-45F0-B431-D4DF69C421CC");
    TaxonomyField field = web.Fields[fieldId] as TaxonomyField;
    string groupName = properties.Feature.Properties["TaxonomyGroupName"].Value;
    string termSetName = properties.Feature.Properties["TermSetName"].Value;
    DiagnosticService logger = DiagnosticService.Local;

    TermSet set = null;
    TaxonomySession session = new TaxonomySession(web.Site);
    TermSetCollection termSets = session.GetTermSets(termSetName, System.Threading.Thread.CurrentThread.CurrentUICulture.LCID);
    if (termSets == null || termSets.Count == 0)
    {
        logger.WriteTrace(1, logger[CategoryId.Deployment], TraceSeverity.Medium,
            "Activity Tags term set not found.  Ensuring '{0}' group and '{1}' term set.", groupName, termSetName);
        // create the term set in the default store
        var store = session.DefaultSiteCollectionTermStore;
        var group = store.EnsureGroup(groupName);
        set = group.EnsureTermSet(termSetName);

        store.CommitAll();
        logger.WriteTrace(1, logger[CategoryId.Provisioning], TraceSeverity.Verbose, "created taxonomy group '{0}' and term set '{1}'", group, set);
    }
    else
    {
        logger.WriteTrace(1, logger[CategoryId.Deployment], TraceSeverity.Verbose, "term set found.");
        // need to make sure we grab the one in the right group, or it might be someone else's term set.                
        foreach (var termSet in termSets)
        {
            if (String.Equals(termSet.Group.Name,groupName))
            {
                if (set == null)
                {
                    set = termSet;
                }
                else
                {
                    logger.WriteTrace(1, logger[CategoryId.Deployment], TraceSeverity.Unexpected,
                        "Multiple term sets named '{0}' found in more than one taxonomy group.", termSetName);
                    throw new SPException(String.Format("Multiple term sets named '{0}' found in more than one taxonomy group.  "+
                                                        "Was there a previous installation that was not removed properly?", termSetName));
                }
            }
        }

        if (set == null)
        {
            // term set found, but in an unrecognized group.  leave it alone and do like above
            logger.WriteTrace(1, logger[CategoryId.Deployment], TraceSeverity.Verbose,
                "Term set '{0}' found, but in unrecognized group.  Provisioning new group and term set as configured.", termSetName);
            var store = session.DefaultSiteCollectionTermStore;
            var group = store.EnsureGroup(groupName);
            set = group.EnsureTermSet(termSetName);

            store.CommitAll();
            logger.WriteTrace(1, logger[CategoryId.Provisioning], TraceSeverity.Verbose, "created taxonomy group '{0}' and term set '{1}'", group, set);
        }
    }

    // set termSets to the newly created term set                
    field.SspId = set.TermStore.Id;
    field.TermSetId = set.Id;
    field.TargetTemplate = String.Empty;
    field.AnchorId = Guid.Empty;
    field.Open = true;
    field.AllowMultipleValues = true;
    field.Update();
}

第二个功能包含列表模板和实例，其中一个使用上述内容类型;我们将此功能称为功能B 。

以下是配置时发生爆炸的列表的列表架构（ListInstance元素未显示）：

<?xml version="1.0" encoding="utf-8"?>
<List xmlns:ows="Microsoft SharePoint" Title="My List" FolderCreation="FALSE" Direction="$Resources:Direction;" Url="Lists/MyList" BaseType="0" xmlns="http://schemas.microsoft.com/sharepoint/">

      <ContentTypeRef ID="0x0100b61c774f4c0e4a89bf230cbb44cd4f75"></ContentTypeRef>
    </ContentTypes>

        <ViewFields>
          <!-- <FieldRef Name="Tags"></FieldRef> -->
          <FieldRef Name="_Comments"></FieldRef>
        </ViewFields>
        <Query>
          <OrderBy>
            <FieldRef Name="ID">
            </FieldRef>
          </OrderBy>
        </Query>
        <ParameterBindings>
          <ParameterBinding Name="NoAnnouncements" Location="Resource(wss,noXinviewofY_LIST)" />
          <ParameterBinding Name="NoAnnouncementsHowTo" Location="Resource(wss,noXinviewofY_DEFAULT)" />
        </ParameterBindings>
      </View>
    </Views>

      <Form Type="NewForm" Url="NewForm.aspx" SetupPath="pages\form.aspx" WebPartZoneID="Main" />
    </Forms>
  </MetaData>
</List>

解决方案部署后，我可以毫无问题地激活功能A 。将创建站点列和内容类型。当我尝试激活功能B 时，功能激活调用堆栈会爆炸并导致出现错误页面，其中包含以下堆栈跟踪：

[COMException (0x80004005): Cannot complete this action.

我很确定我在功能A 中配置TaxonomyField的方式有问题;它在配置时与列表实例的关联是错误的原因（我通过注释掉片段并反复部署来确定这一点）。 TaxonomyFields似乎只有很少的文档，甚至博客经验，并且在列表实例中配置它们，所以我有点不知所措。有人知道出了什么问题吗？

Answer 1

我跟随WictorWilénHow to provision SharePoint 2010 Managed Metadata columns并且能够得到类似的工作（确保也可以从this comment进行修改。）

Answer 2

我最终向微软公开了一个支持事件，以解决这个问题。最终，他们的服务代表将其跟踪到设置列表模板上的属性DisallowContentTypes="FALSE"和列表架构上的EnableContentTypes="TRUE"。这解决了我的配置问题。

但是，我仍然有一个问题，即能够在新配置的列表上实际创建项目，这与必须伴随分类字段（grrr）的隐藏文本字段有关。我在网站中配置了一个注释字段，我在列表模板中引用了它，并且我已将TextField属性设置为网站列定义和字段定义中此注释字段的ID。

Wictor提到了这一点（如果我从阅读他的帖子中回忆起来的话），但这里有更多内容：http://www.sharepointconfig.com/2011/03/the-complete-guide-to-provisioning-sharepoint-2010-managed-metadata-fields/

我目前停留在项目创建时抛出的异常，说：

无法获得“标签”的值 “托管元数据”中的列场类型控制。详见登录。异常消息：无效字段名称。 {956a1078-ec35-4c04-83c4-0a3742119496} http://server/sites/mysite /位点/ mysite的/列表/个

Answer 3

在为包含自定义ContentTypeRef的沙盒自定义列表模板激活包含ListInstance元素的沙盒功能时，我遇到了同样的错误。列表已创建，但创建时出现功能错误。此外，该列表包含自动生成的内容类型，而不是列表定义中指定的内容类型。如果您在创建所有列表之前一直尝试激活该功能，该功能将最终激活。

此外，我注意到我无法从MOSS 2010中的SandBoxed解决方案更新沙盒自定义字段属性。我得到相同类型的错误，表明在通过XML定义的自定义字段上调用SPListItem.UpdateField时无法完成操作在沙盒解决方案中。

我现在得出的结论是，MOSS 2010的沙盒解决方案不支持沙盒字段更新。

您应该在XML字段定义和列表模板字段XML元素中完全定义字段，而不是以编程方式更新沙盒自定义内容类型中的字段。

让您的列表使用自定义内容类型并激活而不会导致＆＃34;无法完成此操作的方法＆＃34;错误如下：

1）在列表定义中使用默认ContentTypeRef，而不是您创建的自定义ContentRef。

https://msdn.microsoft.com/en-us/library/office/ms452896(v=office.14).aspx

例如： 0x01默认项目内容类型

0x0101默认文档内容类型

在List Schema.xml文件中，如果您的内容类型基于默认项目内容类型，则您将其更改为：

<ContentTypes>
    <ContentTypeRef ID="0x01"></ContentTypeRef>
</ContentTypes>

2）将功能激活的事件接收器添加到运行代码的功能，以配置列表的内容类型。

我编写了一个函数，它基本上为列表设置了内容类型，并删除了与列表关联的任何其他内容类型。您的功能激活事件接收器可以运行此功能，并将列表的内容类型设置为应该的列表。以下函数假定您的内容类型具有唯一名称。如果需要，您还可以添加对内容类型组名称的检查。

       public static string ConfigureCustomListForCustomContentType(SPWeb web, string strListName, string strCustomContentTypeName)
    {
        StringBuilder sbOutput = new StringBuilder();
        try
        {
            SPList customlist = web.Lists[strListName];

            SPContentType CustomContentType = null;
            //Validate Content Types
            //1) Find the Content Type in the Content Type list
            foreach (SPContentType spct in web.Site.RootWeb.ContentTypes)
            {
                if (spct.Name == strCustomContentTypeName)
                {
                    CustomContentType = spct;
                    break;
                }
            }

            if (CustomContentType == null)
            {
                sbOutput.Append("<div class='error'>Unable to find custom content type named " + strCustomContentTypeName +".</div>");
                return sbOutput.ToString();
            }
            sbOutput.Append("Found content Type "+CustomContentType.Name+"...<br />");

            Boolean bFoundContentType = false;


            customlist.ContentTypesEnabled = true;

            List<SPContentTypeId> RemoveContentTypeList = new List<SPContentTypeId>();
            //Remove all other content types
            foreach (SPContentType spct in customlist.ContentTypes)
            {
                if (spct.Name == strCustomContentTypeName)
                {
                    bFoundContentType = true;
                }
                else
                {
                    RemoveContentTypeList.Add(spct.Id);
                }

            }


        if (!bFoundContentType)
            {
                sbOutput.Append("Adding [" + strCustomContentTypeName + "] to List " + customlist.Title + "<br />");
                customlist.ContentTypes.Add(CustomContentType);
            }
            else
            {
                sbOutput.Append("[" + strCustomContentTypeName + "] already in List " + customlist.Title + ".<br />");
            }

            for (int i = 0; i < RemoveContentTypeList.Count; i++)
            {

                sbOutput.Append("Removing extra content type: " + customlist.ContentTypes[RemoveContentTypeList[i]].Name + "<br />");
                customlist.ContentTypes[RemoveContentTypeList[i]].Delete();
            }


        }
        catch (Exception ex)
        {
            sbOutput.Append("<div class='error'>Error occurred configuring "+strListName+": " + ex.ToString() + "<br /></div>");
        }

        return sbOutput.ToString();

    }

这应该允许您实例化列表并将内容类型设置为自定义内容类型。

如果列表基于事件类型0x0102，则上述函数可能无法在沙盒解决方案中导致错误。

对于事件类型，我使用默认的事件内容类型并运行代码以根据需要自定义列表（添加列）。

尝试使用站点TaxonomyField设置列表实例时，“无法完成此操作”
