Converting a Boost actor_lexer to static: Error as if "actor_" not used

Question

I'm converting a Boost Spirit Lex program to the static lexer model. The lexer has a semantic action, therefore the dynamic lexer is of type actor_lexer:

#ifndef USE_STATIC_SI_LEXER
    typedef lex::lexertl::actor_lexer<token_type> lexer_type;
#else
    typedef lex::lexertl::static_lexer<
        token_type,
        lex::lexertl::static_::lexer_si
    > lexer_type;
#endif

Now when compiling with the static lexer, I get the error

boost/spirit/home/lex/lexer/lexertl/static_lexer.hpp(230): 
error C2039: 'add_action' : is not a member of 'boost::spirit::unused_type'

which is exactly what is expected when one uses a semantic action but forgets to change lexer into actor_lexer. I did use the actor_lexer type in the generator program, which seems to work as far as I can tell.

Is there something else I'm missing? Or is it currently impossible to use semantic actions in a static lexer?

@llonesmiz YES! this did it. Please make it an answer. (This should really be on the page I linked, though.) — Felix Dombek, Jan 10 '18 at 21:09
@FelixDombek I'm certain you could make a better answer than me(please do), I just looked at the examples and found that. — llonesmiz, Jan 10 '18 at 21:15

There is a static_actor_lexer template for use in this case, as seen in this example.

lex::lexertl::static_actor_lexer<
    token_type, lex::lexertl::static_::lexer_wcl
>
