Hi [~hailong wang], could you give an example where the expected class and
result class are inconsistent.
After going through the pull request, I don't think this is a bug. The Period
literal is a value of {{YearMonthIntervalType}} which represents the number of
months. So the corresponding primitive type of Period is {{Integer}}, you
should use {{getValueAs(Integer)}} or {{getValueAs(Period)}} if the valueClass
is Period.
