What is the definition of a document's parent?

[karl_harris_]

More specifically, how do I differentiate between the immediate parent and the parent of the parent(grandparent) when using the JAVA code below?

DocumentModel x = session.getParentDocument( input.getParentRef());

where session is the injected session and input is a reference to the current document's DocumentModel.

If I look at x.getType() the type is the parent of the parent (grandparent) not the parent document.

The documents on all three levels are folders (from bottom to top a folder, in a folder, in a folder)

Ok, found out what I was doing incorrectly.

	parentDoc = session.getParentDocument(input.getParentRef()); 

should be

           parentDoc = session.getDocument(input.getParentRef()); 

I was getting the parent of the parent and therefore skipping over the immediate parent document.
