Target contact missing for automatically generated case activities
Some actions on cases leave automatically generated activities in the case activity log, but have no target contacts. Examples: Change case title, change case tags. As a result, they cannot be edited through the user interface. While this is a minor issue, some users may want to leave notes about the activity (for example, why they changed a case title) and therefore need to edit it.
- Open any case in CiviCRM and change the case title.
- Tap edit for the corresponding activity in the activity timeline.
- Tap save.
The dialog will freeze while the CiviCRM logo keeps turning. A fatal error "DB Error: constraint violation" will be filed in the logs.
If you add any contact as a target contact in the database or in the edit screen the error won't appear anymore.
What is confusing, too: When editing the activity the client contact already wrongly shows up as target contact in this dialog and if you'd like to change it there you need to search the contact (the link to choose the client contact below the search field won't do the change here).
The Client contact is filed as target contact by default and connected problems disappear. E.g. editable activities can be saved after edit through UI now.
