Maintaining ActionForm data between Actions

Is there a way I can retrieve the values of a Form in a 2� Action which I set on the 1� Action?

This is my scenario:

Struts-config

1� Action

the Form

The JSP takes the Form values of "listaNoticias" correctly, and submits to another action:

2� Action

And that didn�t work because the form values are lost. Why?

I tried making the scope as session in the struts-config action-path but didn�t work.

The values come up as empty because you may not be sending this arrayList as a parameter during jsp form submit to Action 2 or some error in the jsp. Please post the jsp.

In fact, I�m not sending the ArrayList, and dont want to do it.

From pages I found I though that Form values are maintained through JSP�s without the need of repopulating the Form again, but the ArrayList and all of the multiple fields I have in the form are reseted, or the form is created again for each request.

Is there a way to keep the data in a structs-way without resorting to public variables or whatever?

Thanks to another member I found this:
<bean:define id="name" name="MyForm" property="MyFormField" type="java.util.Collection" />

I have to try that yet, but it makes sense that since MyFormField is in the jsp, the form will take the value in the request.
I find it cumbersome and not very efficient but this monday I have to finish this so...

...It didn�t work. How can I submit the Arraylist then?

This is a trimmed down version of my JSP:

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
 
<html:html>
<bean:define id="listaNoticias" name="NoticiaForm" property="listaNoticias"type="java.util.ArrayList" />
<head></head>
<body>
<html:form action="/noticias">
<TABLE ALIGN="center" WIDTH="60%">
<logic:iterate id="elemento" indexId="index" name="NoticiaForm" property="listaNoticias" type="noticias.modelo.bean.NoticiaBean">
    <TR>
***** This is the link that takes me to the action in which I want to use the ArrayList "listaNoticias" ******
    <TD><html:link action="detalleNoticia" paramId="i" paramName="index"><bean:write name="elemento" property="asunto"/></html:link></TD>
<c:if test="${mostrarEditarAdmin}">
<TD WIDTH="55"><a href="../noticias/adminNoticia.do?accion=2&i=<c:out value="${index}"/>">Editar</TD>
</c:if>
    </TR>
   </logic:iterate>
   </TABLE>
</html:form>
</body>
</html:html>

Sorry about the mess, I�m still learning and merging a lot of things at once.
