ActionForm Does Not Pick Up the Values of the Selected Check Boxes

[JiaPei Jen]

I have a web page that displays check boxes for user to make multiple selection:

<html-el:form action="/message/SelectAndMail">
......
......
<td>
<html-el:checkbox property="recipients[${status.index}].selected" />
</td>
<td>
<html-el:hidden property="recipients[${status.index}].emailAddress" />
<c :-o	 ut value="${recipientBean.emailAddress}" />
</td>
......
......
</html:el>

For testing purpose, I made 6 selections of e-mail addresses among all check boxes displayed, Those 6 e-mail addresses are my friends'.

Then, the SelectRecipientForm.java extends the ActionForm class. In the ActionForm class, the multiple selection of check boxes by users are supposed to populate a String Array.

However, the values of the selected check boxes are not picked up. Here is the code of the SelectRecipientsForm.java:

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
 
public class selectRecipientsForm extends ActionForm
{
    // Map of RecipientField objects.
    private Map recipientFieldMap = new HashMap();
 
    private String[] recipients = new String[0];
    private String[] selectedEmailAddresses;
 
    public RecipientField getRecipients( int index )
    {
       RecipientField recipientField = ( RecipientField ) recipientFieldMap.get( new Integer( index ) );
       if ( recipientField == null )
       {
         recipientField = new RecipientField();
         recipientFieldMap.put( new Integer( index ), recipientField );
       }
       return recipientField;
    }
 
    public String[] getSelectedEmailAddresses()
    {
       List theEmailAddressList = new ArrayList();
 
       Iterator i = recipientFieldMap.values().iterator();
       while( i.hasNext() )
       {
          RecipientField recipientField = ( RecipientField ) i.next();
          if ( recipientField.isSelected() )
          {
             theEmailAddressList.add( "\"" + recipientField.getEmailAddress() + "\"" );
          }
       }
       return ( String[] )theEmailAddressList.toArray( new String[theEmailAddressList.size()] );
   }
 
   public void reset( ActionMapping mapping, HttpServletRequest request)
   {
       recipients = new String[0];
       selectedEmailAddresses = new String[0];
   }
}

Of course, I have this RecipientField.java:

public class RecipientField
{
   private String emailAddress = "";
 
   public String getEmailAddress()
   {
      return emailAddress;
   }
 
   public void setEmailAddress( String newValue )
   {
      emailAddress = newValue;
   }
 
   private boolean selected = false;
 
   public boolean isSelected()
   {
      return selected;
   }
 
   public void setSelected( boolean newValue )
   {
      selected = newValue;
   }
}
