I have a problem with Template Toolkit, more specifically with the WRAPPER directive. I'm using ttree. In my ttreerc I defined a wrapper, let's call it "foo". Then, in one of the pages, I used a redirect() FILTER to produce several pages, each described in a data structure defined in the page. This is very similar to my actual code:

[% categories = [ ... ] %]
[% FOREACH c IN categories %]
    [% FILTER redirect( $c ) %]
        bla bla bla
    [% END %]
[% END %]
[download]

Now, I'd like each category page to use the same wrapper. My first attempt has been the following:

    ...
    [% FILTER redirect( $c ) %]
        [% WRAPPER foo %]
        bla bla bla
        [% END %]
    [% END %]
    ...
[download]

but it does not work, leading to ! file error - recursion into 'wrapper.tt2' in the build phase. Allowing recursion via ttree config leads just to deeper errors.
I think I'm facing a common problem, which I'm trying to solve using the wrong tecnique. What's your advice ? Thank you.
