If you get a DocumentTypeInconsistencyException when setting a part, it
can be because:

 - the part you are trying to add does not belong to the document type
of the document

 - the specified mime type argument (in your code the variable _docName)
is not allowed by the part type

This can be because:

 - some required parts and fields are missing

 - or, if it is not a new document, and the document type has been
modified, the document contains some parts or fields which are not
allowed anymore by the document type

You can skip these checks by passing a boolean false to the save method:
_document.save(false)

Note that in all these cases, the message of the exception contains an
explanation of what exactly is wrong.

Hope this helps.
