How to use checkbox in iterate tag ?

I need to display a table of rows using iterate tag.One of the column is a checkbox with value as an some id. I read that there is no "indexed" attribute available for tag html:checkbox . Then how do I implement this functionality in Struts way . I know we can use JSP and javascript to help me out . But as I need to avoid these as much as possible, please suggest me a way .
Thanx

Try something like this:

Hello I am also trying to use the html:multibox.
My data displays correctly, but it is not updating
the values in my bean when the user selects or deselects a check box.
Here is my JSP:
.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<%@ taglib uri="/tags/struts-bean" prefix="bean" %>  
<%@ taglib uri="/tags/struts-html" prefix="html" %>  
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<HTML><HEAD><TITLE>Untitled Document</TITLE>
<META http-equiv=Content-Type content="text/html; charset=iso-8859-1">
<META content="MSHTML 6.00.2600.0" name=GENERATOR></HEAD>
<BODY>
<html:form action="/WorkerSubmit" >
<table>
 <logic:iterate id="worker" name="workerForm" property="map" >
 
 <tr>
 <td><bean:write name="worker" property="value.name" /></td>
 <logic:iterate id="language" name="worker" property="value.languages" >
 <td>
 <html:multibox name="worker" property="value.selectedLanguages">
 <bean:write name="language" />
 </html:multibox>
 <bean:write name="language" />
 </td>
 </logic:iterate>
 <logic:iterate id="day" name="worker" property="value.days" >
 <td>
 <html:multibox name="worker" property="value.selectedDays">
 <bean:write name="day" />
 </html:multibox>
 <bean:write name="day" />
 </td>
 </logic:iterate>
 </tr>
 </logic:iterate>
 </table>
 <html:submit styleClass="button" property="submit" />
 </html:form>
 
 </BODY></HTML>

The input to the JSP is a map of WorkerBeans.
The WorkerBean has methods for setting the selected days and languages:

private String [] selectedLanguages = {} ;
private String [] selectedDays = {} ; 
private  String [] languages = { ENGLISH, CANTONESE, MANDARIN} ;
private  String [] days = { MONDAY, TUESDAY, WEDNESDAY, THURSDAY,FRIDAY } ;

public String[] getDays() {
return days;
}
public String[] getLanguages() {
return languages;
}

public String getSelectedDays(int index) {

return selectedDays[index];
}
public void setSelectedDays(int index, String value) {
selectedDays[index]= value;
}
public String[] getSelectedDays() {

return selectedDays;
}
public void setSelectedLanguages(int index, String value) {
selectedLanguages[index]= value;
}
public String getSelectedLanguages(int index) {
return selectedLanguages[index];
}
public String[] getSelectedLanguages() {
return selectedLanguages;
}
public void setDays(String[] days) {
this.days = days;
}
public void setLanguages(String[] languages) {
this.languages = languages;
}
public void setSelectedDays(String[] selectedDays) {

this.selectedDays = selectedDays;
}
public void setSelectedLanguages(String[] selectedLanguages) {
this.selectedLanguages = selectedLanguages;
}

The set methods are not being called ( I logged the calls to a file).
Any help would be appreciated.
