Can not import xml backup.

[Artem Grotskyi]

Hi All,

I'm trying to import XML Backup to Confluence and I'm getting this error:

org.springframework.orm.hibernate.HibernateSystemException: null index column for collection: com.atlassian.crowd.model.application.ApplicationImpl.directoryMappings; nested exception is net.sf.hibernate.HibernateException: null index column for collection: com.atlassian.crowd.model.application.ApplicationImpl.directoryMappings

at org.springframework.orm.hibernate.SessionFactoryUtils.convertHibernateAccessException(SessionFactoryUtils.java:597)

at org.springframework.orm.hibernate.HibernateAccessor.convertHibernateAccessException(HibernateAccessor.java:353)

at org.springframework.orm.hibernate.HibernateTemplate.execute(HibernateTemplate.java:375)

.....

Caused by: net.sf.hibernate.HibernateException: null index column for collection: com.atlassian.crowd.model.application.ApplicationImpl.directoryMappings 

Does anybody know what can cause such error and how to fix it?

Confluence is 4.3.6 version.

I had to re-take another production backup and restore it.
And it seems to fix the issue.

Never seen that before... Have you maybe done some mapping such as https://confluence.atlassian.com/crowd/mapping-a-directory-to-an-application-18579599.html?

Hi @Panos,

thank you for your answer.

Unfortunately, I didn't find root cause of that issue.
I had to re-take another backup and then restore it.

And it seems to be working for me!
