Hi Aristotle,

You're right, Root/end action is called twice :

| /auto                   | 0.002877s |
| /admin/auto             | 0.001081s |
| /admin/display          | 0.136538s |
|  -> MycoBiblio::View::TT->process 
      | 0.098517s |
| /end                    | 0.000431s |

...
...

| /auto                   | 0.002108s |
| /admin/auto             | 0.000884s |
| /admin/rg               | 0.053757s |
| /end                    | 0.000521s |

We see that in the first call list, the template is well 
called and process correctly as asked in the 'display' code 
action method.
Then the first 'end' call.

Then as in the 'execute' method from C::A::RenderView, it is 
forwarded to the appropriate view, so in 'display' to 
'C::V::TT'.

Then, in the second 'end' call, nothing is forwarded to any 
view as it is asked in C::A::RenderView 'execute' action.

So this is the behavior I wanted :) even if 'end' is called 
twice.


 From C::A::RenderView
---------------------

sub execute {
     my $self = shift;
     my ($controller, $c ) = @_;
     $self->NEXT::execute( @_ );
...
...
     return 1 if $c->req->method eq 'HEAD';
     return 1 if defined $c->response->body && length( 
$c->response->body );
     return 1 if scalar @{ $c->error } && 
!$c->stash->{template};
     return 1 if $c->response->status =~ /^(?:204|3\d\d)$/;
     my $view = $c->view()
         || die "Catalyst::Action::RenderView could not find 
a view to forward to.\n";
     $c->forward( $view );
};
