sharepoint-2010 - CustomAction button in the clipboard editing panel sharepoint 2010

Question

Hi I'm trying to add my own button in the clipboard group of content editor ribbon in SharePoint. It's not appearing anywhere, here's the xml.

  <?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
 <CustomAction Description="Copy html"
            Id="68275191-272b-4c59-a9ee-ee736f76f2e5"
            RegistrationId="100"
            RegistrationType="List"
            Location="CommandUI.Ribbon"
            Title="Copy html" >
<CommandUIExtension>
  <CommandUIDefinitions>
    <CommandUIDefinition       Location="Ribbon.EditingTools.CPEditTab.Clipboard.Controls._children">
      <Button
          Id="copyHtmlSelection"
          Alt="Copy html"
          Sequence="100"
          Command="CustomRibbonButton_CopyHtml_Command"
          Image32by32="/_layouts/Images/copy_big.gif"
          Image16by16="/_layouts/Images/copy_small.gif"
          LabelText="Copy html"
          TemplateAlias="o1" />
    </CommandUIDefinition>
  </CommandUIDefinitions>

  <CommandUIHandlers>
    <CommandUIHandler
      Command="CustomRibbonButton_CopyHtml_Command"
      CommandAction="javascript:CopySelectedHtml();" />
  </CommandUIHandlers>

</CommandUIExtension>
  </CustomAction>

从 CustomAction 元素中移除 RegistrationId 和 RegistrationType 并清除浏览器缓存。这对我行得通：

<?xml version="1.0" encoding="utf-8"?>sdf
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <CustomAction Description="Copy html"
             Id="68275191-272b-4c59-a9ee-ee736f76f2e5"
             Location="CommandUI.Ribbon"
             Title="Copy html" >
    <CommandUIExtension>
      <CommandUIDefinitions>
        <CommandUIDefinition       Location="Ribbon.EditingTools.CPEditTab.Clipboard.Controls._children">
          <Button
              Id="copyHtmlSelection"
              Alt="Copy html"
              Sequence="100"
              Command="CustomRibbonButton_CopyHtml_Command"
              Image32by32="/_layouts/Images/copy_big.gif"
              Image16by16="/_layouts/Images/copy_small.gif"
              LabelText="Copy html"
              TemplateAlias="o1" />
        </CommandUIDefinition>
      </CommandUIDefinitions>

      <CommandUIHandlers>
        <CommandUIHandler
          Command="CustomRibbonButton_CopyHtml_Command"
          CommandAction="javascript:CopySelectedHtml();" />
      </CommandUIHandlers>

    </CommandUIExtension>
  </CustomAction>
</Elements>
