Pivot table has their own styles, and they are used every time it is refreshed,

Once a pivot table is create they can be changed, but affect all pivot tables in the file.

Dear rking,
This bug has been in ASSIGNED status for more than 3 months without any
activity. Resetting it to NEW.
Please assigned it back to yourself if you're still working on this.

BTW I don't think it is a bug.

Maybe could be a enhancement, if every PT could have their own styles inherited from default pt styles, so a style for particular pt could be changed.

 Hi,

 I've been working with rking on this issue, and I'd like to add some context.

 I understand how pivot table styles are applied - I looked at the source code and understand how Calc is looking for styles based on their name, and apply them when the table is created/refreshed.

 The problem is not about applying custom styles. The default styles were used, and edited to have the expected look.
 The problem is that this was done with an earlier version of LibreOffice (5.2), and then opened in 5.4.

 What happens is that the translations for the LibreOffice pivot styles (in French) have been modified in 5.3, and then again in master.
 See for example the "Pivot Table Value" translation history here : https://translations.documentfoundation.org/fr/libo54_ui/translate/sc/source/ui/src.po#search=PIVOT&sfields=source,target&unit=130435809&offset=0

 Then Calc is now looking for default styles with a different name than those found in the document. Since it doesn't find them, it re-creates them with the new name, completely empty. Those new styles are then applied, and the user see the styles disappear.

 Looking for a hard-coded string is causing the problem: whenever the string changes (for a typo, or a translation), you loose everything.

 NOTE: it is similar to the bug described here (https://bugs.documentfoundation.org/show_bug.cgi?id=44763), except we're not moving the document between different locales environments, but from one version of LibreOffice to another.

 From a user's standpoint, without creating any custom styles, this really looks like a bug.

 I understand the problem is not an easy one and won't have an easy fix. But is there a way to fix this bad reference in a document (other than manually renaming each style in every document)?
 Something we could apply as a batch on all existing documents for instance ?

Cédric made a patch on Writer about issue using translated names few years ago. Perhaps you could check those modifications.

ODF are XML zipped so you can easily create some scripts to modify documents.

Ps : it's easier to check bugs when an example document is provided.

Dear rking,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
 
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword
