[Maypole] extending edit template for beerdb?

[Carsten Øland Madsen]

Hi

I'm trying to extend the edit template for the BeerDB demo so that when 
editing beers a list of pubs will be availabe and it will be possible to 
add and remove pubs.

Currently I'm struggling with getting a list with all the pubs from 
within the edit template.

My template code looks like this

FOR accessor = classmetadata.related_accessors.list;
        "<p><select name=\""; accessor | ucfirst;  "\" multiple size=4>\n";
# if stuff missing here with accessor
        FOR thing = config.loader.find_class('pub').retrieve_all();
            "<option value="; thing.id; ">"; thing.name; "</option>\n";
        END;
        "</select></p>";
    END;

Why does the

config.loader.find_class('pub').retrieve_all();

call not return a list with all the pubs?

The find_class returns 'BeerDB::Pub'.
