submit a LIST in struts

Hello Experts,

I'm programming JSP with Apache Struts and I haven't been able to find the way to submit a List property of the form to the next JSP

My case is the following:

I have a JSP (agentInteractions.jsp) where data is modified, this jsp is popoulated with a List property with the following code:

  <c:forEach items="${immunizationScheduleForm.agentInteractionsList}" var="agentList">
    <tr>
    <td align="center" class="lightgray">
       <html:radio name="agentList" property="interactionAgentKey" value="true"/>
    </td>
    <td align="left" class="lightgray">
      <html:select name="agentList" property="ruleCode">      
        <html:option value="1"><bean:write name="agentList" property="ruleDesc"/></html:option>      
     </html:select>
    </td>
    <td align="left" class="lightgray">
       <html:select name="agentList" property="ruleCode">
          <html:option value="1"><bean:write ame="agentList"property="interactionAgentDesc"/></html:option>
      </html:select>      
    </td>
    <td align="left" class="lightgray">
        <html:select name="agentList" property="interval">
           <html:option value="1"><bean:write name="agentList" property="interval"/></html:option>
        </html:select>&nbsp;      
        <html:select name="agentList" property="intervalUnits">
             <html:option value="1"><bean:write name="agentList" property="intervalUnitsDesc"/></html:option>
        </html:select>      
      </td>
    </tr>
  </c:forEach>

this jsp will go to the corresponding action, but when I get there, data from {immunizationScheduleForm.agentInteractionsList is NULL

I already tried to submit this property thru a hidden field (<html:hidden name="immunizationScheduleForm" property="agentInteractionsList " ?> but I get an error

I believe probably there's an special way to submit list property's

Thanks for your help. Urgent

Could you pass your entire JSP with the corresponding ActionForm here?

Additionally, you are naming all the select boxes with the same name i.e. agentList.

        <html:select name="agentList" property="interval">
           <html:option value="1"><bean:write name="agentList" property="interval"/></html:option>
        </html:select>&nbsp;      
        <html:select name="agentList" property="intervalUnits">
             <html:option value="1"><bean:write name="agentList" property="intervalUnitsDesc"/></html:option>
        </html:select>

Thanks, I have found out a way to do it
for Each field in the List, I mapped a corresponding String[] property in the FormBean

ex:
List listVar;
   imagine list with 2 fields: field1, field2

we add the following propertys in the FormBean (ActionForm)
  String[] listField1
  String[] listField2

on the .jsp I mapped the fields
  <c:forEach items="${formBean.listVar}" var="listName">
    <html:select name="FormBean" property="listField1">
    ......
    <html:select name="FormBean" property="listField2">
    .......

And I get those arrarys populated with all the <select> values in the Action Class

Regards,
Glad that you solved it by your own.

Shall I ask the page editor to remove this question and refund the points back to you?

I have antoher issue regarding this same matter.
I have succesfully send all the values selected to the corresponding action.
Now I've been strugling populating the <html:select> with the corresponding values retrieved.
The situation is as follows:
I have all the values set in the corresponding arrays, which are
* scheduleAgentKey
* interactionAgentKey

My jsp is as follows
  <c:forEach items="${immunizationScheduleForm.agentInteractionsList}" var="agentList">
      <tr>
    <td align="left" class="lightgray">      
       <c:out value='${agentList.scheduleAgentKey}' />      
       <html:select name="immunizationScheduleForm" property="scheduleAgentKey" value="">      
                  <html:option value="1">scheduleAgent 1</html:option>
                  <html:option value="2">scheduleAgent 2</html:option      
            </html:select>
      </td>
    <td align="left" class="lightgray">
            <html:select name="immunizationScheduleForm" property="ruleCode">      
                  <html:option value="1">ruleCode 1</html:option>      
                  <html:option value="2">ruleCode 2</html:option>      
            </html:select>
      </td>
</c:forEach

I have found out that if i'm able to put the value I want to be selected in the <html:select value="valueToBeSelected"> it will work, but know the problem is:

HOW do I escape the value of agentList.scheduleAgentKey to this value property?

I already tried this
<html:select name="immunizationScheduleForm" property="scheduleAgentKey" value="${agentList.scheduleAgentKey} ">

And values were no selected properly (it just select the default value)

I already <c:out value="${agentList.scheduleAgentKey} "/> and the value is printed, but some how is not escaped in the select tag

Please help!!!
