[Dancer-users] bug with multiple "template" calls ?

[damien krotkine]

Hi Assaf,

Well, the standard way of doing waht you wish to do is to use these
line of codes instead of using template :

    my $template_engine = engine 'template';
    my $html = $template_engine->apply_renderer(...);
    my $html_with_layout = $template_engine->apply_layout($html);

I can see that the new release is causing you a problem, as it breaks
something that used to work.

I'll see with Sawyer and other core devs what we do. On top of my head
what we can do is either :
- just amend the documentation, and advertise a bit the potential issue
- change back the behaviour of template, and re-release
- perform the old behaviour if 'template' is called in a contexte that
is anything but 'void', and issue a warning

any other idea ?
