howto multilingual autocomplete ?

Dear Developer-List,

I would like to have multilingual autocompete fields in my zms.
therefore I have several items beginning with in the language  
dictionary (IN_1, IN_2, and so on)
and - as it works for select fields - I thought it might work for  
autocomplete fields as well:

here my code:
##################

<dtml-call "REQUEST.set('IN',[])"
 ><dtml-let lang_dict="getLangDict()"
 ><dtml-in lang_dict sort=key
 ><dtml-if "_['sequence-item']['key'].find('IN_') > -1"
 ><dtml-call "REQUEST['IN'].append(getLangStr(_['sequence-item'] 
['key'],lang)+'\n')"
 ></dtml-if
 ></dtml-in
 ></dtml-let
 ><dtml-return "''.join(REQUEST.get('IN'))">

################

unfortunatly this does not work :(

Any idea how to fix this?

best regards,
Thorsten Weber
