Hello,
I have a problem when iterating over the results of an object method
that returns its results dependant on wantarray.
The problem only shows, when the result contains only a single element
and a vmethod like reverse is called (see example below).
This is what seems to happen: TT calls mainobject->subobjects in list
context and gets a list with only one element. When reverse is called on
this element it is inspected found to be a hash_ref, converted to a
hash, converted to an array and that array reversed -- wich obviously is
not the desired result.
Is there a way to tell TT to either take the result as an array no
matter how many results there are OR force a scalar context on the
mainobjects.subobjects call?
I already tried .list and a check on .size both don't work because they
do the same unhelpful conversion(?).
I also wanted to give Template::Stash::Context a try but don't know how
to change my code to use it correctly. When I tried, I always got an
error that SubObject doesn't have a reverse-method.
Thanks for any help

here is a complete example that demonstrates the problem:
#!perl -w
package MainObject;
sub new { bless {}, shift }
sub subobjects {
my $data = SubObject->new();
my @data = ($data);
# no problem when there are more than 1 subobjects
return wantarray ? @data : [EMAIL PROTECTED];;
}
package SubObject;
sub new { bless {somevalue => '2008-01-01'}, shift}
sub somevalue {
return shift->{somevalue};
}
package main;
use strict;
use Template;
my $template = Template->new();
$template->process(\*DATA, {mainobject => MainObject->new()});
__END__
# Does work:
[% FOREACH subobject IN mainobject.subobjects %]
[% subobject.somevalue %]
[% END %]
# Doesn't work:
[% FOREACH subobject IN mainobject.subobjects.reverse %]
[% subobject.somevalue %]
[% END %]
