  From: John Napiorkowski =

    This is the error message you get if you create a subclass of Catalyst:=
:View that doesn't implement a process() method.  It probably doesn't have =
anything to do with the name of the module...

      I have tried:

      perl script/myapp_create.pl view Show

      After restarting the application, it gives that error. If I do instea=
d:

      perl script/myapp_create.pl view Html

      The application works fine after restarting it. Am I doing something =
wrong?

      Thanks.

    I'd personally be interested in seeing what the generated files look li=
ke.  Could you attach them in your response (or post them someplace we can =
see?)

    Hi,

    Here is the first one (Show.pm):

    package TranzactiiBursiere::View::Show;

    use strict;
    use warnings;
    use base 'Catalyst::View';

    =3Dhead1 NAME

    TranzactiiBursiere::View::Show - Catalyst View

    =3Dhead1 DESCRIPTION

    Catalyst View.

    =3Dhead1 LICENSE

    it under the same terms as Perl itself.

    =3Dcut

    1;

    And here it is the second one that works (Html.pm):

    package TranzactiiBursiere::View::Html;

    use strict;
    use warnings;
    use base 'Catalyst::View';

    =3Dhead1 NAME

    TranzactiiBursiere::View::Html - Catalyst View

    =3Dhead1 DESCRIPTION

    Catalyst View.

    =3Dhead1 AUTHOR

    =3Dhead1 LICENSE

    =3Dcut

    1;


    If I just delete the file Show.pm and restart the server, the program w=
orks fine, but if I put it back and restart, it gives that error.
    I have seen the same thing under Linux and Windows.

    Thanks.


  As others have pointed out, when you use $c->forward(...) that target nee=
ds a process method.  I try to think of modules that I forward to as being =
implementations of the "Command" design pattern, or part of a Pipeline patt=
ern, instead of a module that is actually instantiated and consumed.  At le=
ast that's the way I try to make sense of all the different ways you can ac=
cess Catalyst modules.

  I'm guessing that the reason Html works is that you actually have a diffe=
rent Html modules or Action somewhere in the path that works correctly, and=
 it is that module and not the new one you are creating that is getting cal=
led.

  When I forward to a view I try to be very explicit like:

  $c->forward($c->view('html')) || $c->log->error("Can't find the html view=
.");

  I find this helps.  So try looking in your list of installed components t=
o see if Html is being matched someplace else.  Also please let me know wha=
t you goal here is, that way maybe we can advise a bit better.  Good Luck
