We recently had a client run into a strange issue we had never come across before.
Certain activities could not be edited or deleted.
When deleting you would get an event log error of:

The issue is that in the entity events of the activity area for both updating and deleting, there is code to check the USERNOTIFICATION table and perform business logic. When these activities have that code checked, they contained an unexpected value in the USERNOTIFICATION.TYPE field. This field is an enumerated property in the entity model. This means that it translates the text value into a defined numeric value based on the enumeration definition.
There were a handful of activities that had a non-matching TYPE value. We were not clear how they were added but they had been created years ago.
I ran a query to find non-matching values:
select distinct type from sysdba.USERNOTIFICATION where type not in ('New','Change','Deleted','Confirm','Decline','Unknown','Leader','Completed','Removed')
In this case it was only a single non-matching value used for some USERNOTIFICATION records. A result of “Delete”.
For those non-matching values I created a update SQL statement to change those to a valid Type enumeration value, like this:
update sysdba.usernotification set type='Deleted' where type='Delete'
After running that, the activities could then be edited/deleted normally.
