    <div class="moz-cite-prefix">Hi again,<br>
      <br>
      As I promised, I'm back for the autocomplete feature with respect
      to multilang fields. And the one with the "problem" is the
      ml_title field. Here's some context:<br>
      <br>
      When I replaced the title field in my workflow, I saw that there
      was an input_lookup_url attribute which was calling the
      autocomplete script named title_duplicates. The existing entry
      was:<br>
      <br>
      &lt;component&gt;&lt;field ref="title" required="yes"
      input_lookup_url="{$config{rel_cgipath}}/users/lookup/title_duplicates"
      input_lookup_params="id={eprintid}&amp;amp;dataset=eprint&amp;amp;field=title"
      /&gt;&lt;/component&gt;<br>
      <br>
      I thought to replace the title string in the url, so I ended up
      with a line like this:<br>
      <br>
      &lt;component&gt;&lt;field ref="ml_title" required="yes"
      input_lookup_url="{$config{rel_cgipath}}/users/lookup/title_duplicates"
input_lookup_params="id={eprintid}&amp;amp;dataset=eprint&amp;amp;field=ml_title"/&gt;&lt;/component&gt;<br>
      <br>
      But when I tested it it didn't work. Looking at the POST request I
      saw that the final call was:<br>
      <br>
<a class="moz-txt-link-freetext" href="http://mysite/cgi/users/lookup/title_duplicates?q=The%20Limits&amp;_text=The%20Limits%20&amp;id=270&amp;dataset=eprint&amp;field=ml_title&amp;field=ml_title&amp;dataobj=270&amp;dataset=eprint">http://mysite/cgi/users/lookup/title_duplicates?q=The%20Limits&amp;_text=The%20Limits%20&amp;id=270&amp;dataset=eprint&amp;field=ml_title&amp;field=ml_title&amp;dataobj=270&amp;dataset=eprint</a><br>
      <br>
      Which resulted in an SQL statement like (from my mysql logs):<br>
      SELECT `eprintid` FROM `eprint` WHERE  `eprint_status`='archive'
      AND `eprintid`!=270 AND `ml_title` IS NOT NULL AND `ml_title` 
      COLLATE utf8_general_ci LIKE 'The Limits%' LIMIT 10<br>
      <br>
      Running it by hand returns the error:<br>
      <br>
      ERROR 1054 (42S22): Unknown column 'ml_title' in 'where clause'<br>
      <br>
      Indicating clearly that ml_title field does not exist in table
      eprint. Which is obviously true.<br>
      <br>
      So, what's the best way of dealing with this problem? By examining
      my database, I saw that EPrints created two additional tables for
      my ml_title field, namely:<br>
      <br>
      - eprint_ml_title_lang<br>
      - eprint_ml_title_text<br>
      <br>
      And in my case, eprint_ml_title_text contains the information my
      script would have to search. So, I could:<br>
      <br>
      1) just copy title_duplicates script to a new one on which I'd
      make the relevant changes to only look into the specific table and
      fields and return something analogous to what the script would
      return, or <br>
      2) write a new script from scratch (not sure why), or<br>
      3) Do something else that I'm missing and is much more elegant
      design and development wise.<br>
      <br>
      If the answer is (1) (which is most probably the case), any
      directions would be welcome. And by directions I mean that if
      someone could tell me which parts to leave out because they won't
      match in our case, it would be nice.<br>
      <br>
      Thanks all in advance,<br>
      <br>
      George.<br>

        False alarm! After I understood what you initially meant, I
        commented out the code of get_value and set_value in
        eprints_fields_local.pl and ran your script again (for both
        get_value and set_value), and this time, for both runs, the
        return value was: <b>NOT DEFINED</b>, which means that you can
        relax now! :):)<br>
        <br>
        But, before finishing with this multilang thing and build the
        Bazaar package, I'll have to address:<br>
        <br>
        1) the search functions to search in the correct fields<br>
        2) the autocompletion feature to run smoothly where applicable<br>
        <br>
        Thanks again!<br>

                                                          So, we need

                                                          using a

                                                          store our

                                                          Now, in order
                                                          for EPrints
                                                          not to break,
                                                          we change the

                                                                                                    field
                                                          to be a
