Summary
Importing from Cloud to an empty Server instance fails producing an NullPointerException
Steps to Reproduce
- Export data from a cloud instance
- Set up or access a test Server instance (7.6.2 is fine to reproduce)
- Attempt to import the data
Expected Results
The import works without problems
Actual Results
The import stops at 90% and then fails producing an error. Tables appear to be partially generated during the process, so a new import requires deleting and recreating the application DB beforehand. If the import was made using the Setup Wizard during a fresh installation, the UI does not display any errors but users won't be able to login afterwards.
The below exception is thrown in the catalina.log file:

Workaround
Manually removing all data relating to AO_575BF5 from activeobjects.xml allows the import to complete successfully:
- Extract the contents of the backup (zip) file.
- Using your preferred text editor, open the file activeobjects.xml.
- Look and delete all the tags containing a reference to the table AO_575BF5. You need to remove each complete entry related to it (see my example image-2018-01-04-19-26-39-993.png
. The example is using a different table, but the principle is the same. The XML file might appear in a format difficult to read, so you might want to do the following:
- For Windows Users: use a text editor that can format the XML to be humanly easier to read and edit, in my case I used Notepad++ with the XML Tools plugin, and used the function 'Pretty print' from the XML Plugin (see my example image-2018-01-04-19-12-05-438.png).
- For Unix based OS, another option to format the XML file is with the command:
xmllint --format activeobjects.xml > activeobjects_formatted.xml
- For Windows Users: use a text editor that can format the XML to be humanly easier to read and edit, in my case I used Notepad++ with the XML Tools plugin, and used the function 'Pretty print' from the XML Plugin (see my example image-2018-01-04-19-12-05-438.png

You will need to rename the activeobjects_formatted.xml back to activeobjects.xml before zipping them.
-
- Once all the entries related to the table AO_575BF5 have been removed, save the file and create a new zip file using the newly saved activeobjects.xml and the original entities.xml.
- Attempt the Restore System again.
