submitting map-backed action forms

[Olve Sæther Hansen <ol...@uib.no>]

Given the following form, I am using a map backed form, basically as 
described in:
http://struts.apache.org/userGuide/building_controller.html#map_action_form_classes 


This form is in the QuestionGroupAction class as this:
* @struts.action name="mapValueForm" path="/answerQuestionGroup"
* parameter="action" scope="request"
*
* @struts.action name="mapValueForm" path="/openQuestionGroup"
* parameter="action" scope="request"

and the form is a part of openQuestionGroup.do.

<html:form action="answerQuestionGroup" method="post" 
styleId="mapValueForm" >
<c:forEach var="question" items="${requestScope.questionList}">

<h4><c:out value="${question.title}"/> </h4>
<i><c:out value="${question.question}"/></i>
<div>
    <%--    Todo: legg til innrykk--%>

<c:forEach var="alternative" items="${question.alternatives}">

<html-el:radio  value="${alternative.id}" 
property="value(${question.id})"/>
<%-- Here I am trying to get the value from mapValueForm --%>

<c:out value="${alternative.text}" />  <br>
</c:forEach>

</div>
<div class="separator"></div>
</c:forEach>

<html:submit styleClass="button" property="action" onclick="bCancel=false">
    <bean:message key="button.answerQuestionnaire"/>
</html:submit>
</html:form>

Everything works except submitting the form. How can I hook the 
properties from the radio button to the map form?

I found some suggestions to put idName="mapValueForm" (my form name):
<html-el:radio  value="${alternative.id}" property="value(${question.id})"/>
to
<html-el:radio  value="${alternative.id}"  
property="value(${question.id})" idName="mapValueForm"/>

which instead of the previous error gives me this one (3 is the id of
one of the radiobuttons, fetched from db and set correctly):

javax.servlet.jsp.JspException: No getter method available for property
3 for bean under name mapValueForm

I have struggled with this problem a few days now.. Hope anyone who can 
help me?

I have read some messages on this list  concerning almost the same 
problem. They gave me enough help to get where I am now, but now I am 
completely stuck, and a bit fed up with struts (or at my incompetence)...

Thanks,
