In my SharePoint 2013 solution I have created a custom managed metadata field definition. The field has the attribute ShowInFileDlg set to False, so I expect the column does not show up in the document information panel. When opening a new Word document the column does show in de document information panel. Other field types (text, choice) with the ShowInFileDlg set to False are not showing.
I found some people saying this is a SharePoint bug, but cannot find a good confirmation. Does anybody know if this is in fact a SharePoint bug? Or does anyone have a good workaround for this problem?
