Open xml relationship target is NULL when inserting chart

Question

Hi,
I have looked into the specification ISO/IEC 29500-1:2012 and i understand that the attribute Target for the element Relationship can be set to NULL at times(Empty header and footer in the specification).
Now, i have stumbled on Target being NULL also when inserting a diagram into a word document. For example:
<Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/oleObject"
Target="NULL" TargetMode="External" xmlns="http://schemas.openxmlformats.org/package/2006/relationships" />
I'm using Open xml sdk and i'm trying to create a relationship. My question is how i should resolve the target which i think should point to the diagram/chart that i inserted.

Answer 1

Hi Cindy,
It is "easy" to reproduce :)
1. Create a word document
2. Add a CustomXml to the document with for example "Word content control toolkit"
2:1 The CustomXml should look something like this <Root xmlns=http://schemas.company.se><Description></Description></Root>
3. Open up the word document and open up the "XML Mapping Pane" under Developer tab. Add rich text content control which mapps to the <Description> element.
4. Save and close the document
5. Take a copy of thedocument
6. Open up the document again, place the insert point within the content control mapped to <Description> element and insert a Chart.
7. Save and close the document
8. Rename the document with the extension .zip and navigate to word/charts/_rels/ and open up chart2.xml.rels.
9. Search for Target="NULL", you should find 1 occurrence
