--- Comment #30 from Winfried Donkers <o...@dci-electronics.nl> --- (In reply to comment #24) > I gambled a little around with 3.4.5 (WIN) and "fdo39484-sample", ... We have not noticed grouping/notes losses with versions prior to 3.6.4 (all Windows), except possibly once (with version 3.5.something) in November 2012. > a) is it 100% clear when the loss happens? In our cases, all losses happened when the document was saved and was noticed when openened the next time. That is to say, grouping (sometimes notes as well) gets lost on a complete sheet, which need not necessarily be the sheet in view. So in some cases, the loss of grouping/notes was only noticed some time later. The groupings (notes) are simply not saved for that sheet, I examinated several backups and studied the xml-content. > b) Am I right that normally only some groups are lost and replaced by hiding > the rows / columns, but normally not all? It may be that I do not understand your question, but when it happens _all_ grouping (rows and columns) are gone on a sheet. I cannot say whether it happened on one sheet only or or one or more sheets, but it did not happen on all sheets. The sheet(s) with lost grouping (notes) were often not the selected/visible sheets. > c) do we have any document set showing a before/after loss. I would prefer > something like Winfried Donkers' sample what is simple enough for quick > tests (might be with macro aid) Yes, I have several documents before and after as we have a lot of backups. I cannot upload them as they are (the documents include information from customers) to freedesktop. I can upload one or more fods with sensitive information removed, I can also send them (ods) as an attachment to Rainer or Petr directly on the condition that they are used discretely. > d) due to "fdo39484-sample.ods" contains hundreds of ODF errors. Are sample > documents with valid ODF 1.2 (strict) available? The documents with which we experienced the grouping/notes loss were all xls-docuemnts (Excel 2000) that were converted to odt in the autumn of 2010 and used with LibreOffice since. So yes, ODF-errors can be expected in the documents. I include 'notes' when I say grouping, as the loss of notes occurs together with the loss of grouping (in the same tab). I cannot say with certainty that grouping loss did not occur without notes loss, but the other way round (notes have not been lost without groups being lost) is definitivelt true. We have 8 people editing a total of 20-100 of calc-documents like the fdo39484-sample. Some are edited several time a day, some only once a year. We only noticed the data loss since December, 2012 and only found two documents which suffered data loss (we checked more than 50 of these documents that were modified in November/December 2012 and January 2013). One of these two documents, suffered data loss several times. My suspect is that it is a combination of document-content (ODF-error?) and FILESABE handling of LibreOffice. The people that edit these two documents regularly have downgraded to version 3.5.7. Since then we have not noticed grouping/notes losses. As it looks to me that it is document-related, the ratio with which the bug happens could be less than 1/1000 for documents in general or 1/10 (a guess) for susceptible documents. -- You are receiving this mail because: You are the assignee for the bug.
