[Xerte-dev] Re: Data Loss: Any idea?

[Ron Mitchell]

Were you able to compare preview.xml and data.xml?

Is it defintely the same LO or could it me an older copy?

Anythng in the recycle bin of the same name?

 

As you say everytime I've seen this it's also been because the xml has been
broken - never that whole pages have dissapeared without the xml being
broken. Sometimes it's been possible to recover the lo by removing the
broken preview.xml and replacing with a copy of data.xml or manually closing
the broken section. I can't see how it's possible to lose pages without the
xml being broken but sounds like it is?

 

A while back Alistair was having regular problems with broken xml and in the
end it seemed to be due to broadband connection problems.

 

Any automated server backups? Indeed could someone have overwritten the
later version during a restore?

Subject: [Xerte-dev] Data Loss: Any idea?

 

I have a user who reports having 29 pages in an LO when she last closed it,
now there are only 17.

 

The file is a complete xml file with opening / closing <learningObject> tags
intact, and doesn't appear to be a fragment, or to be cut off in the middle.
The XML passes the W3C validator.

 

Any idea what could have happened to cause the pages to get lost? This is a
more advanced user, and the LO has some custom mark up in I (which I did)
but I didn't experience any issues building the templates. Every other data
loss situation I have come across has been with a file that just ends
somewhere in the middle. I've never seen a fully intact xml file and have
the user report lost data before.

 

I'm at a bit of a loss really.
