That seems absolutely wrong, and besides fixing it we also should integrate an test into [ConstantsDemo.thrift|https://git-wip-us.apache.org/repos/asf?p=thrift.git;a=blob;f=test/ConstantsDemo.thrift;hb=HEAD] [~DavinC], what specific questions that I can answer do you have? was (Author: jensg): Confirmed, trying this ends up in a "{{cannot use "test" (type string) as type *string in field value}}".
