New subject: [xwiki-users] Problem with "save" action on objects (org.hibernate.StaleStateException)

24 Aug 2006

Dear all,

I've recently migrate my XWiki installation to an other server after a hard 
drive crash.

I've copied my XWiki installation as it was and upgrade from Tomcat 5.5.15 to 
Tomcat 5.5.17.

Tomcat is able to start correctly however the behaviour of XWiki has been 
affected since I can't anymore use the "save" action on an object.

For instance, if I reach the "Class Editor" page (XWiki.XWikiClasses) :
- click on "PhotoAlbumClass" to create a new photo album
- create a new photo Album called "Photos.MyAlbum"
- I can see a form but if I enter a title and a description and then I save, I 
get a blank page without any object attached.
- I have the following errors in my logs :

10:06:59,441 ERROR TP-Processor30 
http://manage.objectweb.org/xwiki/bin/save/Photos/MyAlbum 
AbstractBatcher:doExecuteBatch:60 - Exception executing batch:

...

AbstractFlushingEventListener:performExecutions:277 - Could not synchronize 
database state with session
org.hibernate.StaleStateException: Batch update returned unexpected row count 
from update: 0 actual row count: 0 expected: 1
...

Does somebody know what is wrong is my configuration ?
