template toolkit question -- metadata

[madison.sacd]

Dear Monks,

I am trying to show different title in template.

In my controller list.pm, I assign a type variable to the template.

$c->stash->{type} = 'B';

In the template, according to the type, the metadata "title" will be assigned different value, "Book" or "CD". My problem is that I got correct debug output for each condition. However, "CD" will always be assigned to the metadata "title". In other words, when I pass type 'B' to template, the debug output shows "!!!!!!!!!!", which is correct, but the title displays "CD". Anything wrong with my code?

[% IF type == 'B';
     META title = 'Book';
     debug("!!!!!!!!!!");
     debug(type);
   ELSE;
     debug("@@@@@@@@@@");
     debug(type);
     META title = 'CD';
   END;
-%]

The TT2 documentation says:

The META directive allows simple metadata items to be defined within a template. These are evaluated when the template is parsed

That means that the last value assigned to a META item will 'win', so to speak, as the conditional can't be and isn't evaluated during parse-time - change the order of the conditional, and the title should always display "BOOK".

Edit: I experimented a bit with the following template

[% SET type = "D" %]
[% IF type == 'B';
     META title = 'Book';
   ELSIF type == 'D';
     META title = 'DVD';
   ELSE;
     META title = 'CD';
   END;
-%]
- [% template.title %] / [% type %]  / [% template.name %] / [% templa
+te.modtime %] -
[% META title = 'LAST' %]

and ttree to test my hypothesis, and I seem to interpret the documentation correctly:

- LAST / D  / test.tt2 / 1178881986 -
