[Templates] INCLUDE and passing hash as arguments

[H S]

Hi,

I have  a hash passed from CGI::App to my main template which I want to pass that hash to another template.    I can't get to work.  It is ok if I pass as a scalar but not the hash.

I've got this error:
Error executing run mode 'main': undef error - Template::Stash::XS: get (arg 2) must be a scalar or listref at /dssweb/template/events/batch_monitor_main.tmpl line 26. at /dssweb/apache2/cgi-bin/events/monitor line 9

Any suggestions?  thanks, Isarin

[batch_monitor_main.tt]
        [% tmpl_dist = 'events/batch_monitor_search_by_district' %]
        [% INCLUDE $tmpl_dist  districts = districts %]     ### districts is hash,  Isn't 'districts' already a listref? 

[batch_monitor_search_by_district]
<form action="" method="post" class="noSpace">
select a district: &nbsp;&nbsp;
<select name="dist">
        [% FOREACH district_cd = districts.keys.sort %]
        <option value="[% district_cd %]">[% districts.$district_cd %] [[% district_cd %]]</option>
        [% END %]
</select>
<input type="hidden" name="rm" value="ld">

</form>
