capture does not use within directory

hello group,

When I run this Capfile

require 'capistrano/setup'
require 'capistrano/deploy'

namespace :erik do
    desc "deploy on eriks pc"

    task :rvm do
        on roles( :app) do |host|
            within '/data/archief/current/rails' do
                versie = capture( 'rvm current' )
                puts 'version is ' + versie
                execute 'rvm', 'current'
            end
        end
    end
end

I get this output, which  shows that the capture command is NOT using the within dir (whereas the following execute does):

Who can explain what I'm doing wrong?

thanks in advance, Ruud

 Found it. A similar post made me try the capture without spaces, with an array, like

  versie = capture( 'rvm', 'current' )

Which DOES work, that is, the command is prepended by a cd. Not sure if this is a bug, or a feature. Nevertheless I'm glad I got it working.

        on roles( :app) do |host|
            within '/data/archief/current/rails' do
                versie = capture( 'rvm current' )
                puts 'version is ' + versie
                execute 'rvm', 'current'
            end
        end

output is now (snippet)
