Journal Work Notes and Comments on Task-extended tables are not added to the Activity Stream on the table form.
Steps to Reproduce
1. Create a new table with a journal entry field or use an installed plugin like GRC Vendor Risk Management.
2. Upgrade it to a currently supported release.
Observe the Activity(filtered) field does not work on task forms.
This is expected behavior, by design the Activity Formatter does not get added automatically for custom tables extending task, it needs to be manually added from the form layout list collector slush-bucket:
1) Right-click in the form header and choose Configure > Form Layout.
2) Move the Activities(filtered) field from the right bucket into the left bucket, and then add it back to the right bucket.
3) Click Save.
