OK - without trying it out :-) What happens is that as you get the outlines from the attachments and add them to the root of your outlineRoot and overwrite the document catalog the objects the childs are pointing to are not yet part of the document as the actual merging is done afterwards. So you need to rearrange the outline after you have merged the documents.
