[gradebook2-dev] Missing right part of gradebook

[Juan Arcadio Martínez Cárceles]

Hi,

this is Juan Arcadio from Universidad de Murcia, we are having a unusual 
behavior in one site, we are using GB2 1.6.1

A few days ago, a teacher called us saying that the right part of 
gradebook was missing (I attach an image). She didn't grade any student, 
therefore we solved it moving this "x-file" gradebook to a test site (We 
made changes in GB_GRADEBOOK_T) and a new gradebook was created in the 
next access to her site.

After that, the teacher entered the site and she was grading her 
students, and some days later it happened again, the teacher lost the 
right part of gradebook.

If we enter as admin to the site we can see it all, but if we enter as 
the teacher (su) the right part of graddebook is missing and we get this 
error in the browser console:
- Error: uncaught exception: java.lang.NumberFormatException: For input 
string: "28.83331298828125"

In SAKAI_EVENT table we have realized that the last event before the GB2 
was broken is "gradebook2.export" event, we tried to reproduce this 
error in a test server, but we are not able.

Has anyone had this strange behavior??


Thanks in advance,
Juan Arcadio.
