Alternating Header

[kebeaner]

Hi, I'm trying to get alternating headers to work

Code: Select all

      HeaderPart headerPartOdd = new HeaderPart();
      HeaderPart headerPartEven = new HeaderPart();

      Relationship relOdd = wordMLPackage.getMainDocumentPart().addTargetPart(headerPartOdd);
      Relationship relEven = wordMLPackage.getMainDocumentPart().addTargetPart(headerPartEven);

      ObjectFactory objectFactory = new ObjectFactory();

      // create header content using a header open xml skeleton
      String headerTextOdd = getXMLString("header_text_odd");
      String headerTextEven = getXMLString("header_text_even");
      // headerText = headerText.replace("productName", productName);
      
      Hdr hdrOdd = (Hdr) XmlUtils.unmarshalString(headerTextOdd);
      Hdr hdrEven = (Hdr) XmlUtils.unmarshalString(headerTextEven);
      
      headerPartOdd.setJaxbElement(hdrOdd);
      headerPartEven.setJaxbElement(hdrEven);

      List<SectionWrapper> sections = wordMLPackage.getDocumentModel().getSections();
      SectPr sectPr = sections.get(sections.size() - 1).getSectPr();
      if (sectPr == null) {
         sectPr = objectFactory.createSectPr();
         wordMLPackage.getMainDocumentPart().addObject(sectPr);
         sections.get(sections.size() - 1).setSectPr(sectPr);
      }

      // set header reference
      HeaderReference headerReferenceOdd = objectFactory.createHeaderReference();
      headerReferenceOdd.setId(relOdd.getId());
      headerReferenceOdd.setType(HdrFtrRef.DEFAULT);

      HeaderReference headerReferenceEven = objectFactory.createHeaderReference();
      headerReferenceEven.setId(relEven.getId());
      headerReferenceEven.setType(HdrFtrRef.EVEN);

      sectPr.getEGHdrFtrReferences().add(headerReferenceEven);
      sectPr.getEGHdrFtrReferences().add(headerReferenceOdd);


but only the "even" header is showing up.
I can't seem to figure out why

[jason]

What does the sectPr resulting XML look like?

sections.get(sections.size() - 1).setSectPr(sectPr); looks a bit dodgy...

DocumentModel has a refresh method:

sections.get(sections.size() - 1).setSectPr(sectPr); in reference to https://github.com/plutext/docx4j/blob/ ... reate.java

Code: Select all

// create header part and set relationship
      HeaderPart headerPartOdd = new HeaderPart();
      Relationship relOdd = wordMLPackage.getMainDocumentPart().addTargetPart(headerPartOdd);
      ObjectFactory objectFactory = new ObjectFactory();

      headerPartOdd.setJaxbElement(hdrOdd);

      String headerTextEven = getXMLString("header_text_even");

      Hdr hdrEven = (Hdr) XmlUtils.unmarshalString(headerTextEven);

      // set header reference
      HeaderReference headerReferenceEven = objectFactory.createHeaderReference();
      headerReferenceEven.setId(relEven.getId());
      headerReferenceEven.setType(HdrFtrRef.EVEN);
      sectPr.getEGHdrFtrReferences().add(headerReferenceEven);

      wordMLPackage.getDocumentModel().refresh();


This only shows the even header

edit

the sectPr looks like that it should not have the same relationid right?

<w:sectPr>
<w:headerReference w:type="even" r:id="rId2"/>
<w:headerReference w:type="default" r:id="rId2"/>
<w:footerReference w:type="default" r:id="rId3"/>
<w:pgSz w:w="11907" w:h="16839" w:code="9"/>
<w:pgMar w:top="1440" w:right="1440" w:bottom="1440" w:left="1440"/>
</w:sectPr>

when breaking up the document with the webapp into parts, it also has does not contain a second header.xml file

Edit 2

If you have graphics in your header and you're loading it from and XML format. There doesn't seem to be a way to properly link the graphic file to the header via

XmlUtils.unmarshalString();

At this point it may be easiest if you post a complete standalone class with main method which I can run to see what is going on.

But, the note:

I suspect what is happening is that with new HeaderPart(), you are using the default part name, so you need to call addTargetPart with param AddPartBehaviour.RENAME_IF_NAME_EXISTS

The default is what it is, for now ancient backward compatibility reasons

If you have graphics in your header and you're loading it from and XML format. There doesn't seem to be a way to properly link the graphic file to the header via

You need to add the image part to the header part first, which will give you a rel id. For example, assuming BinaryPartAbstractImage imagePart, you'd do headerPart.addTargetPart(imagePart)

Then use that rel id in your XML, in attribute a:blip/@r:embed

[kebeaner]

The AddPartBehaviour successfully added the different header files! Hooray!

Code: Select all

      // create header part and set relationship
      HeaderPart headerPart2 = new HeaderPart();
      Relationship rel = wordMLPackage.getMainDocumentPart().addTargetPart(headerPart2, AddPartBehaviour.RENAME_IF_NAME_EXISTS);

However it does not automatically show up, (it'll show up if you go into document and manual turn on even/odd headers). I did some comparison between the two documents and I found that "evenoddheader" did not show up in the original settings.xml

Code: Select all

               <w:settings>
            <w:zoom w:percent="50"/>
            <w:defaultTabStop w:val="720"/>
            <w:evenAndOddHeaders/>

The line creates a nullpointerexception error when executed.. is there a specific location which to use it in?
getdocumentSettingsPart returns null

edit

Also how would you set "first page" different header as well?

[jason]

The one liner assumes you have a document settings part, containing at least the CTSettings element. If you don't, you'll get an NPE.

It relies on the part shortcut being set, which is done as the docx is read into docx4j, or when addTargetPart is used, so either way, it *should* to be set.

What is the stack trace?

Also how would you set "first page" different header as well?

Add the titlePg element to your sectPr

I'm creating a document from scratch, not reading it in to docx4j.

      // Creates Objectfactory and gets the sectPr of the document

wordMLPackage.getMainDocumentPart().getDocumentSettingsPart().getContents().setEvenAndOddHeaders(new BooleanDefaultTrue());

Causes NPE at get contents because documentsettingspart is null.

[jason]

OK, well you need to:

- create new DocumentSettingsPart
- add content to it (a CTSettings object)
- add it to your MDP (addTargetPart)

Everything worked out right! Thanks for everything!
