Hi again,
$c is automatically passed to Catalyst-actions (not methods), but only
if you use Catalyst to do so.
If you call
$self->someaction;
or
$c->controller('SomeController')->someaction();
it is not passed. How can catalyst know if you are calling a catalyst
action, or any method on any object? And even if the object is a
catalyst controller, how can catalyst know if it is a action, which
requires the context, or just a helper, which doesn't use the context?
If you want catalyst to pass $c, use $c->forward, $c->detach, $c->visit
and $c->go instead:
$c->forward("/someaction");
or
$c->forward($c->controller('MyController')->action_for("someaction"));
or
$c->forward("/somecontroller/someaction");
Read the main catalyst docs for details. (perldoc Catalyst)
