Hidden numbering for headers

Hi there,

Just tried 5.0.1 and 5.0.2 RC1 and got a regression with DOC format: numbered headers not displayed.

Please, open the attached file in LO4 and then LO5 and you'll spot the difference: headers do not have numbering.

Furthermore, they are treated as numbering, i can change the style, but when i save, close and open it again, the style is lost and is not shown.

I'e been trying to play with styles (imported with document and default), sometimes LO5 saves the style when it's one of the default ones, but not sure when that happens.  

LO4 works with these styles less or more correct.
LO4 says these headers have WW8Num8 style, while LO5 says it has WW8Num1 style. (see the attached screenshots)

Thank you in advance.

Comment 3 Andrew Kornilov 2015-09-17 19:29:00 UTC
Just tried this:

1. Opened the attached DOC in LO5.
2. Applied the style WW8Num8 to the first heading
3. Saved it as ODT.
4. Opened that ODT in LO5 and everything was OK.
5. Then saved that new ODT file as a new DOC file
6. Opened that new DOC file and that heading missed the numbering again.

So it seems to me something is different when parsing numbering from DOC files.
Comment 4 Andrew Kornilov 2015-09-18 12:57:29 UTC

I have three copies (a little bit different) of that document. In one of the copies i can't also save the line spacing value. It's always 105%.  I change it in the style settings, change across text for all paragraphs, save it, open and the spacing is again 105%.

I tried to export to ODT, change line spacing, save it and open again - everything is OK. Then i exported that ODT to DOC and it also had correct line spacing.

Please, check it, i'm attaching the document.

Confirmed with attachment 118806 [details]. displays the heading numbers ok, while 5.0.2 loses them.

Opening in LO error doesn't manifest on first page but still occurs on third page with the header number not appearing for what should be Section 3. Also, the numbering for the numbered paragraphs in the section is out of sequence.

Number was seen in LO 4.2 (and as explained in 4.3) and still not in LO 6.5+.

Comment 21 Justin L 2021-04-15 06:21:55 UTC
Is this a clue? I used Word 2003 to round-trip the file as DOCX, and Heading1 doesn't have an ilvl value.
  <w:numId w:val="2"/>

(In the DOCX, the numbering/level is direct assigned to the paragraph - perhaps done by the round-tripping? Using a new version of Word to RT might be better.)

This one looks like a different problem than the others - an inheritance problem. It inherits from Heading 2. So in Word it would be at level 2, but in Writer, there is no level inheritance from "Chapter Numbering" styles - so in this case a  special effort would need to be made to copy the OutlineLvl setting from the parent style, I think.

> *** Bug 104239 has been marked as a duplicate of this bug. ***
Oops - I mixed the two up. This one is the real comment 19 test_numerotation.doc.

In this one, Titre 1 (heading 1) really does not specify a numbering list (sprmPIlfo) or a listlevel (sprmPIlvl), only an outline level (sprmPOutLvl). So there is no numbering associated with this style.
Instead, the numbering is applied directly on all four paragraphs using sprmPIlfo listId 1.

Titre 2 specifies outlineLevel 1(aka 2), ListLevel 1 (aka 2), and listId 1 (same as the heading1 paragraphs).

That causes a problem, because LO uses a secret, internal list for Chapter Numbering (Heading 2-10) which is not available for Direct Properties. (I think there is a way for numbering styles to share a list - which is how this would have to play out.)
Comment 24 Justin L 2021-04-16 17:56:52 UTC
comment 0's "numbered headers example.doc" is different again.

In this one, Заголовок 1 is Heading 1, and it defines outlinelvl=0, ilvl=0 (twice) and ilfo numId as 1 and then 2.
<rgtchar value="Heading 8"/>
<istd value="0x8"/>
<sprm value="0x2640" ispmd="0x40" fSpec="0x1" sgc="paragraph" spra="1" name="sprmPOutLvl" operandSize="1" operand="0x7"/>
<sprm value="0x260a" ispmd="0xa" fSpec="0x1" sgc="paragraph" spra="1" name="sprmPIlvl" operandSize="1" operand="0x7"/>
<sprm value="0x460b" ispmd="0xb" fSpec="0x1" sgc="paragraph" spra="2" name="sprmPIlfo" operandSize="2" operand="0x1"/>
<sprm value="0x260a" ispmd="0xa" fSpec="0x1" sgc="paragraph" spra="1" name="sprmPIlvl" operandSize="1" operand="0x7"/>
sprm value="0x460b" ispmd="0xb" fSpec="0x1" sgc="paragraph" spra="2" name="sprmPIlfo" operandSize="2" operand="0x2"/>

In addition, the paragraph seems to have direct formatting setting ilvl to 0, ilfo to 8.
<transformed value="ОБЩИЕ ПОЛОЖЕНИЯ\x0D"/>
<bxPap type="BxPap" offset="3149" size="4608 bytes">
<istd value="0x1"/>  #paragraph style #1 - aka heading 1
<sprm value="0x260a" ispmd="0xa" fSpec="0x1" sgc="paragraph" spra="1" name="sprmPIlvl" operandSize="1" operand="0x0"/>
<sprm value="0x460b" ispmd="0xb" fSpec="0x1" sgc="paragraph" spra="2" name="sprmPIlfo" operandSize="2" operand="0x8"/>  #numId eight

But apparently the numbering style is set to NONE(instead of decimal, romanLower, letterUpper etc) for the numbering list 2 (aka Heading 1). So that part is all correct.
<lvl type="LVL" index="1" offset="14147">   #numID=2
<lvlf type="LVLF" offset="14147">
<iStartAt value="0x1"/>
<nfc value="0xff"/>  #if nfc is equal to 0xFF or 0x17, this level has no number sequence, and the level number of the paragraph is an empty string.

The numbering style for numId 8 (LVL 63-71) specifies decimal numbering.
<lvl type="LVL" index="63" offset="17904">
<lvlf type="LVLF" offset="17904">
<iStartAt value="0x1"/>
<nfc value="0x0"/>  #decimal

It seems as if the direct formatting is being removed, because the numbering can be controlled by changing the Chapter Numbering number type.

This is "fixed" by commenting out //bAppliedChangedOutlineStyle = true;

Comment 26 Justin L 2021-04-19 15:48:27 UTC
The problem is in RegisterNumFormatOnTextNode
    if (bSetAttr && pTextNd->GetNumRule() != pRule
        && pTextNd->GetNumRule() != m_rDoc.GetOutlineNumRule())
Well, the textnode has been assigned the outlinenumrule, so this is skipped. Basically, it means that you can't override a heading style's numrule.

What needs to happen is to capture the original DOC numrule (in this case numId 2) and compare it to the one being assigned (in this case numId 8).
