Clever trick required

Hi all

Bean 1 has a property, a list of Bean 2s.

I want to display these on the screen but I don't want to display repeated occurrences of 
the same value from Bean 1.  For example, lets assume Bean 1 is surname and Bean 2 
is first names, and we have families, and what I want is something like:

Smith		Tom
    Mary
    Freddy
Jones		John
    Liz
    Jim
    Wendy

What I get is:

Smith		Tom
Smith		Mary
Smith		Freddy
Jones		John
Jones		Liz
Jones		Jim
Jones		Wendy

My code is simple:

<logic:notEmpty name="family">
<logic:iterate name="family" type="Family" id="aFamily">
   <logic:notEmpty name="aFamily" property="members">
   <logic:iterate name="aFamily" property="members" type="Member" id="aMember">
      <tr>
        <td>
           <p>
             <jsp:getProperty name="aFamily" property="name"/>
           </p>
        </td>
        <td>
           <p>
             <jsp:getProperty name="aMember" property="name"/>
           </p>
        </td>
      </tr>
   </logic:iterate>
   </logic:notEmpty> 
</logic:iterate>
</logic:notEmpty>

How do I change this to achieve what I want????  There must be a simple trick for 
doing this.

Kind regards
mc

displaytag does it, and it's in sample screens on sf.net.
displaytag should be included in struts!
Also... using logic tag is deprecated. use jstl instead.

Hi mate :-),

using the indexId property in the second logic:iterate and displaying
<jsp:getProperty name="aFamily" property="name"/>
only if indexId is 0 would do waht you want?

A possible solution could be:
 <logic:notEmpty name="family">
<logic:iterate name="family" type="Family" id="aFamily">
<logic:notEmpty name="aFamily" property="members">
<bean:define id="firstRow" value="true" />
<logic:iterate name="aFamily" property="members" type="Member" id="aMember">
<logic:notEqual name="firstRow" value="true">
<tr>
<td>
<p>
<jsp:getProperty name="aMember" property="name"/>
</p>
</td>
<td>
<p>&nbsp;</p>
</td>
</tr>
</logic:notEqual>
<logic:equal name="firstRow" value="true">
<tr>
<td>
<p>
<jsp:getProperty name="aFamily" property="name"/>
</p>
</td>
<td>
<p>
<jsp:getProperty name="aMember" property="name"/>
</p>
</td>
</tr>
<bean:define id="firstRow" value="false" />
</logic:equal>
</logic:iterate>
</logic:notEmpty>
</logic:iterate>
</logic:notEmpty>
