Here is what I am doing :
I have a Bean with a vector field...
public class SearchResult implements Serializable {
private Vector lots = new Vector();
... and a method returning an array of the vector's elements ...
public Lot[] getLots() {
Lot[] results = new Lot[lots.size()];
lots.copyInto(results);
return results;
}
In the JSP I can use the iterate tag as follow :
<logic:iterate id="lot" name="searchResult" property="lots">
...
<bean:write name="lot" property="number" filter="true"/>
...
</logic:iterate>
Hope this helps

______________________________
as far as i know you can have nested iterate tags:
<logic:iterate id="outerObj" name="beanX" property="OuterCollection">
<bean:write name="outerObj" property="name/>
<logic:iterate id="innerObj" name="outerObj"
property="InnerCollection">
<bean:write name="innerObj" property="name"/>
</logic:iterate>
</logic:iterate>
i think the trick is referencing the page scope var you've created
in the outer iterate... in this case "outerObj".
