CAP::AutoRunmode forwarding problem

An app. I was developing some time ago seems to have stopped working 
properly. The problem seems to involve methods in a CAP::AR delegate 
class, which run correctly except when I try to forward to another 
sub-routine. Let me illustrate:
package MyApp::Runmodes;
use strict;

sub runmode_1 {
  my $self = shift;

  $self->check_rm( 'mysub_1', $params )
  || return $self->dfv_error_page();

  # do more stuff, then goto mysub_1() in same package:
  $self->mysub_1; # causes fatal error - see below
}

Fatal error:
Error executing run mode 'runmode_1': Can't locate object method 
"mysub_1'" via package "MyApp" at /path/to/myapp.pm line 169.
$self->forward('mysub_1') gives this:
Error executing run mode 'runmode_1': CAP::Forward: target method 
mysub_1 of run mode mysub_1 does not exist at /path/to/MyApp/Runmodes.pm 
line 169.
__PACKAGE__->mysub_1 finds mysub_1() OK, but gives:
Error executing run mode 'runmode_1': Can't locate object method "param" 
via package "MyApp::Runmodes" at /path/to/MyApp/Runmodes.pm line 219.
Strangely, __PACKAGE__->mysub_1($self) doesn't work but mysub_1($self) 
does, but it does not feel correct to write it like that.
There is an entry in the CAP::AutoRunmodes documentation under security 
about making sure that "when using a delegate object, that it (and its 
superclasses) only contain run modes (and no other subroutines)". Does 
this explain why I am seeing this apparently strange behaviour (if so 
why?), or am I missing something more obvious?
