Cannot inline edit when there is a different mandatory column

[blizzz]

1. Go to a view where there is one column with a mandatory value
2. The view already has rows (with that column filled)
3. Try to change another value inline

Expected: Save

Actual: Errors and the log line: An internal error or exception occurred: Mandatory column \"Foobar\" cannot be empty.
