Bug 81331

Created attachment 102756 [details]
Example file that already saved to DOC

Created attachment 102757 [details]
Next example with 2 styled lists (in ODT format, save it to DOC)

Here is another example that demonstrates the problem with 2 numbered lists - screenshot is here http://i.imgur.com/dtvimOY.png

The formatting of list items in DOC file appears shifted by 1 item backwards in Word.

This is because the MS Binary / OOXML formats do not support named list styles (these are defined in ODF only). Refer this thread for further detail:

There is nothing LO can do about this. I think this bug can be RESOLVED as NOTABUG.

Owen Genat, thanks for the info, very useful.
As I understand, main problem is "OOXML doesn't support named numberings", so this issue can not be fully solved, but list of related problems can be minimized.

Main and very annoying problem is when user mark only one item of long list as bold/italic in ODT, in DOC file we got all list styled with this one item style.

So if I use list with 100 items, and mark item 91 as bold, in DOC I will see all list with bold style, this is the main problem. Losting style of item #91 is not so serious problem.

If we cannot store style info for separate item, why we style all list via style of separate item?

Can we cleanup all custom styles of items in list and use defaul style (or first item style) for all list when exporting to DOC? 

This way will considerably decrease described problem and minimize visible differences in odt and doc file.

Thanks for clarifying the issue. One thing to note is that the provide ODT examples do not use list styles e.g., ListN or NumberingN.

The WWNumN list styles appear to be created by the DOC export filter according to the formatting of the identifier, rather than the list item. Attachment 102755 [details] only has bold and regular identifiers, thus WWNum1 (bold) is created when saving that attachment to DOC format. The result however is that all list items end up with bold identifiers and thus use the WWNum1 list style.

In attachment 102757 [details] there are bold, italic, and regular identifiers and again, saving this file to DOC results in three list styles. The styles however in the DOC appear to be WWNum2 (bold+italic), and WWNum3 (Bold) in keeping with the resultant identifier appearance.

This explains why, when one of these WWNumN styles is subsequently modified, it affects numerous list items. Exactly why there is a difference between identifier display and apparent definition in the ODT and that in the DOC is unclear. I must admit however that I find list style definitions in DOC/DOCX difficult to determine so this bug really needs a developer to assess it and see what (if anything) is feasible.

This report is therefore not so much about the naming of the WWNumN list styles as it is about how list styles of this type (name) are defined / translated when saving to DOC. I am therefore going to confirm this. Status set to NEW. Summary edited for clarity. Apologies for any initial misunderstanding of the issue.
