[Zope] tokens and multiple in sqltest

[milos.prudek@worldonline.cz]

I'm baffled by Zope behaviour with multiple option of sqltest.

I have a Z SQL method list_art_writers:
--- list_art_writers ---
SELECT fname, lname FROM writers WHERE <sqltest m_id type=nb multiple>;
--- end ---

This method has a single parameter: m_id:tokens

This ZSQL method works perfectly when called from a test interface.


It also works OK when called from a form:
--- list_art_form ---
<form action=list_art_method>
<input name="m_id:tokens">
</form>
--- end ---

... where list_art_method is simply:
--- list_art_method ---
<dtml-in list_art_writers><dtml-var fname></dtml-in>
--- end ---

but, but.... when m_id is not gathered from a form, but is rather a
datasheet "m_id" property of a ZClass "ORL_Art" (the type of this
property is tokens), it does not work:

--- list_art_writers ---
  <dtml-in expr="objectValues('ORL_Art')">
  <tr> 
    <td valign="top">&dtml-a_id;</td>
    <td> <a href="&dtml-absolute_url;"
target="_parent">&dtml-title;</a></td>
    <td>
    <dtml-in list_art_writers>
           <dtml-var fname><dtml-unless sequence-end>,</dtml-unless>
    </dtml-in>

    </td>
    <td>&nbsp;</td>
    <td>45%</td>
  </tr>
  <tr> 
    <td>&nbsp;</td>
    <td colspan="4"><font size="-2"><dtml-var abstract></font></td>
  </tr>
  </dtml-in>
--- list_art_writers

The list_art_writers works fine, except for <dtml-in list_art_writers>
section, which gives:
