3.2.1 Import Files Error
Dear OpenMeetings Community,
We were wondering if this issue is fixed in 3.2.1:
https://issues.apache.org/jira/browse/OPENMEETINGS-1603
We are getting an error. The use case and log are below. We would
appreciate any vector to solve this issue.
-------------
USE CASE
-------------
We imported our db from 3.1.5 to 3.2.1.
Then, we accessed 'My files (home drive)'.
The screen gives "internal error" .
When we click on the 'Room files ' or 'Public files', we do not get any
error.

Re: 3.2.1 Import Files Error
Posted by Maxim Solodovnik <so...@gmail.com>.
After import you have File with type == null
This is weird
please check your DB and backup XML files
if you fill everything is OK please privately share your backup with me and
I'll try to check/fix
