Can’t insert iWork files into Container, which is generated with latest iWork
You can insert iWork file into container, which is generated by iWork 09 old version, but you can not insert files generated with latest iWork.
The file may be bundled. When you control-click the iWork file in the Finder, do you see "Show Package Contents" in the context menu? If so, compress (zip) it first before inserting into the Container field.
