This is a followup to let everyone know what has happened with Kris' export issue.

The error in the log was:

16:33:56,965 [http-0.0.0.0-8080-3:] ERROR org.lamsfoundation.lams.learningdesign.service.ExportToolContentService - org.lamsfoundation.lams.util.zipfile.ZipFileUtilException: An error has occurred while trying to zip the files. Error message is:
16:33:56,965 [http-0.0.0.0-8080-3:] ERROR org.lamsfoundation.lams.authoring.web.ExportToolContentAction - Unable to export tool content: org.lamsfoundation.lams.learningdesign.service.ExportToolContentException: org.lamsfoundation.lams.util.zipfile.ZipFileUtilException: An error has occurred while trying to zip the files. Error message is:

Now, this error isn't very helpful! I have tried to improve the error in LAMS 2.0.1 so hopefully if it reoccurs it will give us more of an idea.

The problem was related to a file uploaded using the HTML editor in authoring. For some reason, the code that creates the export file (which is a zip file) couldn't get the uploaded file. We checked and the file did exist on the server. They tried deleting the problem file and re-uploading the file into the learning design and then they were able to export the learning design just fine.

So it looks like it is something weird with how their Windows server "hangs on" to files. We are still looking into what it could be that triggered the problem, but we don't think it is an issue with LAMS itself.

If anyone encounters a similar problem, particularly with 2.0.1 (due real soon now!) can you please post?

Fiona
