BUG: restore from failed

When I try to restore the confluence site it gives me the error: null index column for collection: com.atlassian.crowd.model.application.ApplicationImpl.directoryMappings

I checked the contents of entities.xml and found that listIndex was handled incorrectly, which eventually led to an exception.


xml content:

<object class="DirectoryMapping" package="com.atlassian.crowd.model.application">
<id name="id">163841</id>
<property name="allowAllToAuthenticate">true</property>
<property name="listIndex" column="list_index">0</property>


After restoration, list_Index is set to null.

mysql> select * from cwd_app_dir_mapping;
+--------+----------------+--------------+-------- ---+----------------+
| id | application_id | directory_id | allow_all | list_index |
+--------+----------------+--------------+-------- ---+----------------+
| 163841 | 98305 | 131073 | T | NULL |
+--------+----------------+--------------+-------- ---+----------------+

Before restore, the value of list_index is 0, if I set it to 0 manually, confluence will work fine.

mysql> select * from cwd_app_dir_mapping;
+--------+----------------+--------------+-------- ---+----------------+
| id | application_id | directory_id | allow_all | list_index |
+--------+----------------+--------------+-------- ---+----------------+
| 163841 | 98305 | 131073 | T | 0 |
+--------+----------------+--------------+-------- ---+----------------+
1 row in set (0.01 sec)


I checked the hibernate configuration and found that it seems that the correct cloumn is not configured for listIndex?

Hi @Jack Wu welcome to the community.  I took at quick look at Atlassian's Jira site ( and didn't find anything that resembles this issue, but I could have missed it. 

If the exporting isn't creating indexes correctly, you may want to contact support ( and get some feedback from them.
