From the code examples in the cgiapp_init and cgiapp_prerun sections in
the manual (2.4) I assumed that all runmodes defined in the SUPER
class, when defined in that class's setup() method, would be
automagically inherited by the application class. Not so, apparently.
Maybe it goes without saying that the above
$self->SUPER::cgiapp_init(@_) should be used to actually effectuate the
inheritance, but I think it might be a valuable addition to the manual.
And then, why does this work from within cgiapp_init() and _not_ from
within setup()?
Anyway, I solved the problem by no longer defining my functions by
_reference_ in the setup() method (thanks Shaun, and Brian too, for
pointing me to the docs again ;-) ), and by 'forcedly' inheriting
runmodes with the above cgiapp_init().
This inheritance mechanism is wonderful. I enjoy C::A more and more each
time I use it!
