Yea, there are a lot of half finished classes in XWPF. Fields are one of those.
If you look at Stack Overflow here https://stackoverflow.com/a/40264237/2296441
you will see how I add a table of contents as a simple field. This should be
relatively easy to add as a method of a paragraph like this:
Public XWPFSimpleField createSimpleField(String instruction) {
CTP ctP = p.getCTP();
CTSimpleField field = ctP.addNewFldSimple();
field.setInstr(instruction);
return field;
}
Then you would add a table of contents like this: para.createSimpleField("TOC
\\h");

Subject: XWPFFieldRun Doesn't Work for Creating DOCX
When creating new DOCX the XWPFFieldRun class does not work to create
paragraphs with CTSimpleFields.
The problem is that the field is not written out during commit. The current
unit test only tests the read path but does not test the write path, which
would fail.
I'm not sure what the right solution is (or I would have simply implemented it).
This code works:
CTSimpleField ctField = para.getCTP().addNewFldSimple();
((XmlObject)ctField).newCursor()
.setAttributeText(
QNAME_INSTR_ATT,
fieldData);
So it's not a critical issue but it's definitely an annoyance in the API that
you can't create simple fields directly.
I don't have time at the moment to puzzle through this so I was hoping somebody
might have more cogent ideas about how best to address this in the API.
But my fear is that addressing this would require serious adjustment or
extension to the internals of XWPFParagraph.
Ideally I'd like something like:
XWPFSimpleField field = para.createSimpleField("PAGE");
I'd also like XWPF-level support for creating complex fields, but that's more
involved due to the amorphous nature of complex fields, so I'm really not sure
what design should be.
Thanks,
Eliot
