grails how to output message in tag lib

Question

I'm trying to pull in a message from message.properties from a taglib, but the output is empty. I know the taglib is being called because if I output out << 'hello' it works fine. And my code is defined because if I change the codename to something that doesn't exist in the properties file my IDE highlights the code with red text, indicating it wasn't found.

class AccountTagLib {

    def accountType = { attrs, body ->
                out << message(code: 'account.friendlyType.BF')
}
}

message.properties:

account.friendlyType.BF=Here I am

Answer 1

I think it should work like

out << g.message(code: 'account.friendlyType.BF')

At least that is how I always use it (successfully). But I also read that you can omit the namespace for builtin taglibs (see answer Can I use grails tag outside of GSP? ) so that yours should work too. If it does not work as I proposed may be the other answers to that question Can I use grails tag outside of GSP? help.
