This is always bad news. Happily it doesn’t seem to be happening often. From time to time it happens here as well, and almost every time it is because people are pasting in text from MSOffice or elsewhere that carries unseen formatting that breaks the XML, as much as we try and protect it. There is better error handling code in there now than the early days so if you upgrade it may improve – of course, if it’s a rare occurrence, it’s hard to tell.

We do test to see if the xml is well formed, and prevent it being saved if it isn’t, but I think from time to time things do slip though, and when this happens no one can tell us exactly what they were doing when it broke. We hear ‘well, I, er, dunno, but it was working one minute, and not the next… pardon? Paste form word, no, I don’t think so, er, shouldn’t I do that then, oh, I didn’t know that…’ etc, so it’s hard to replicate things and prevent them happening again.

If it happens, the first thing to look at is whether data and preview.xml files are the same. If they are, there’s probably not much you can do about it, but try and see if the xml file contains more info than they are seeing in the editor. If so, some of it might be able to be rescued.

If they are different, you can restore to the last good published place. If you can catch a real example I’d love to see it, because this is about the worst thing that can happen, and it shouldn’t be possible.

Subject: [Xerte] xot data disappearing

Hi – apologies if this has already been covered, but I have now had several incidents of data disappearing from Xerte objects and wondered if this was a known problem, and/or what the solutions might be.

It happens infrequently (4/5 times over the last two versions that we have had installed during the last couple of years), we’re currently on version 1.7.

I think what happens is that data gets corrupted/lost during the saving process. For example the most recent case the LO was about 40 pages and was saved normally, but when we went to open it again it contained only 29 pages.
