Symptoms

Switching to a different language makes the Service Portal widgets fail. There are javascript errors and a Nullpointer Exception seen on the screen and the console log contains the script for the widget that fails.

The following error is seen:

Release

Kingston Patch 9 and onwards.

Cause

This is seen because of bad data in the sys_translated_text table. There can be records with empty Field name and Value columns linked to a document key which also might have the valid translations present as well. When looking for translations, the system can encounter these empty records and throw null pointer exceptions and cause the widget load failure.

Resolution

The simplest way to fix this issue would be to remove the bad data. Deleting these empty records fixes the problem.

These empty records can be found by looking at the node logs and finding the errors thrown when the issue happens. The errors contain the sys id of the document for which the translation caused the null pointer exception. This sys id can be looked for in the document column on the sys_translated_text table to find the empty/bad data.
