deletepart not working?

I have a document with 2 image parts with rId1, rId2.

After mainDocumentPart.DeletePart(rId2), I see the image2 is gone, the entry to rid2 was removed from document.xml.rels under .res. So the imagepart rId2 is gone.

Problem: there is still an entry of rid2 inMainDocumentPart.

Question: Why does notMainDocumentPart.DeletePart(rId2) itself remove the entry rid2?

Or do I still have to parse the XmlDocument of theMainDocumentPart tomanully remove the rid2 entry?

Thanks!

Steve
