Description

When removing a Version with a versionlabel and restoring an other Version from the same containing history within 1 transaction, a NPE occured. When debugging I noticed the method createEventStates was entered with an UUID from a versionLabel. The ChangeLog.get(id) returned null.

Caused by: java.lang.NullPointerException
