Steps to Reproduce

when a sub-category is created or modified, any appearance parameter for default sorting such as calendar, agenda or map doesn’t “work” ie the element appears as selected but the messages are displayed by most recent.
It works after a click on the element for instance calendar and the annexation of l/calendar to the url

worked with beta7 (and precedent commit of events)
