iterate tag help.

[Nani Jon <na...@yahoo.com>]

Hi all:

Is there a way in struts <logic:iterate ... tag to be able wrap the values coming out of a collection (ArrayList) on a JSP? 

Here is a sample of my JSP code which puts everything on the same <td>:

<tr>
        <logic:present name="results">      
         <logic:iterate id="myFormArrayListElement" name="results" property="formArrayList" type="String">
          <td valign="top" colspan="2"><span class="normal">
           <bean:write name="myFormArrayListElement"/></span>
          </td>           
              </logic:iterate>
        </logic:present> 
       </tr>

 

Thanks in advance for your help.

Regards,

Nanijon.

If the elements of the list are just Strings (or other "atomic" types) 
then you won't be able to break them down into sub-properties.  If they 
are composites (i.e. they have getFoo(), getBar(), etc.) you could write 
these properties with:
<bean write name='myFormArrayListElement' property='bar'/>
etc.

Afaik that's what it's for...

You don't need property I think: name="MyArrayList" should name the
ArrayList you want to get iterated, id="newBeanName" is the bean name to
access the single elements of the ArrayList:

<logic:iterate id="result" name=" myFormArrayListElement" type="String">

>           <td valign="top" colspan="2"><span class="normal">
>            <bean:write name="myFormArrayListElement"/></span>

<bean:write name="result"/></span>

>           </td>
>               </logic:iterate>
>         </logic:present>
>        </tr>

I think that should work. A look at the struts developer documentation
explains exactly how to use the struts-tags.
