Description

?first should work for SortedSets given that there's an actual .first() method on the object.

Offending line of code:

<a href="<@s.url action="index" report=(reportsMenu[key]?first).name />"><@s.text name=key /></a>

Working alternative:

<a href="<@s.url action="index" report=(reportsMenu[key].first()).name />"><@s.text name=key /></a>

Stacktrace:
