[ic] UserTag and locale Problem

[Lars Tode]

Hi list,
 
may be some has an idea or a hint for the following problem.
I still did not get it yet.
 
A UserTag, lets call it check_basket, should controll some things like
the minimum order value, the maximum order value and other stuff.
 
If, for example, the total is less then the minimum order value,
check_basket should set the error message "some text" using error:
$Tag->error(
   {
    name  => 'my_error',
    set   => $error_msg
   }
);
 
$error_msg is set in this way
 
my $error_msg    =  $Tag->filter(
   {
    'op'  => 'loc html2text vars_and_comments',
    interpolate => 1,
    body  => 'some text'
   },
   ''
);
 
The locale.txt:
--snip--
code    en_US
some text   Some text [user_tag] again text 
--snap-- 
 
I added $Tag->log() to have a look, what is set in error. It seems that
the UserTag is not parsed.
The log - file contains the follown text message:
Some text [user_tag] again text

If interpolate_html() or $Tag->loc() is used, it produce the same
output.

*help* :-(

Regards,

Lars
