Hai,

$tmpl->param( content => [{ title=>'hi'...body=>'testing'  }] );
[download]

U have used this way.
But try this way, which always works for us.

push(@array, { title=>'hi',body=>'testing'});
$tmpl->param( content => \@array);
[download]

U can use this logic to solve the issue...alter accordingly..
