try 'perldoc HTML::Template' then search for filter... the first thing it says is:
filter - this option allows you to specify a filter for your
template files. A filter is a subroutine that will be called
after HTML::Template reads your template file but before it
starts parsing template tags.
thus, filtering is only applied on file load (ie when the tamplate is parsed for
tags). Since caching wont allow the file to reload unless it changes, the filer is
not re-applied.
To solve this, you can either:
a) disable caching if you want to keep the filter
b) re-implement the template so that you dont need to use a filter, by using TMPL_IF
and TMPL_INCLUDE
Hope this helps,
Mathew
