I have a Content-type 'Reports' containing a field called 'Country' which has allowed values listed in the form:
The field is an integer list so that I can use the 'Multiple Values' option in the View that displays this Content Type (see below)
The View has filters for Published=Yes and Content-type=Reports. It also has a Contextual Filter (Argument) for Content:Country. Visitors on, say the England page have a link to the View which includes /1 at the end of the URL. Likewise, the link on the Wales page includes /2 at the end of the URL etc etc.
The setup for the Contextual Filter has the box ticked for 'Override Title' and the following in the box for the replacement Title:
Reports from %1
The View works correctly and displays the correct Reports, but the Title is displayed as 'Reports from 1'. instead of 'Reports from England'. In other words, it is displaying the Key instead of the Label.
This works correctly in Views 6.x-3.0 which is why I am assuming it is a bug in 7.x-3.3
My Contextual Filter has 'Allow multiple values' ticked so I can use the View to list reports from a selection of countries e.g to display Reports from England and Wales the URL ends with /1+2. This will only work if the key is an integer. Again, the View works correctly and displays the correct Reports but the Title says 'Reports from 1+2' instead of 'Reports from England+Wales.
