[Templates] Lost in Templation

[prev] [thread] [next] [Date index for 2004/06/17]

I'm am once again totally confused by the errors I'm getting when doing a 
_very_ simple process.

Here is the abbreviated code.

    my $sut =
        Template->new({INCLUDE_PATH => ['/root/bin/templates/']});
    my $filename = 'largemail.tt';
    my $msgbody = '';

    $sut->process($filename, \$Size, \$msgbody)
        || die $sut->error();

If I change the array reference '\$msgbody' to a simple scalar '$msgbody'
I get the filled in template returned to the screen.
   '\$Size' is a global and actually an array but using '\%Size' gives me 
errors also but more of them  :-(.

So here is the error I'm getting while running the whole script through
the debugger.  Of all htepermutations I tried this gave me 
the shortest error message.  Where have I gone wrong?

Not a HASH reference at /usr/lib/perl5/site_perl/5.8.0/Template/Service.pm 
line 79.
