Bean population question (Urgent)

Hi all,

I'm sorry for the urgent-tag. But, I have a deadline to make this weekend.

Okay the problem:

I have a ActionForm wich contains a ValueObject. Like this 
(DeleteCorrectionForm):

package nl.informatiefabriek.om.action.correction;

import nl.informatiefabriek.om.correction.value.CorrectionValue;

import org.apache.struts.action.ActionForm;

/**
 * @author harm
 *
 * @struts.form
 *              name = "deleteCorrectionForm"
 */
public class DeleteCorrectionForm extends ActionForm {
        private String id;
        private CorrectionValue correctionValue;
 
 
        /**
         * @return
         */
        public CorrectionValue getCorrectionValue() {
                return correctionValue;
        }

        /**
         * @return
         */
        public String getId() {
                return id;
        }

        /**
         * @param value
         */
        public void setCorrectionValue(CorrectionValue value) {
                correctionValue = value;
        }

        /**
         * @param string
         */
        public void setId(String string) {
                id = string;
        }

}

In my JSP I have to iterate throug a Collection of 'Corrections' like 
this.
The corrections Collection contains CorrectionValueObjects:

<c:forEach items="${corrections}" var="correction">
<html:form action="/delete_correction">
        <html:hidden name="idBean" property="id"/>
        <html:hidden name="correction" property=
"correctionValue.correctionId"/>
        <html:submit styleClass="button" value="Delete"/>
</html:form>
</c:forEach>


This piece of JSP generates this html:

<form name="deleteCorrectionForm" method="post" 
action="/ordermanager-ejb/delete_correction.do">
<input type="hidden" name="id" value="A simple id">
<input type="hidden" name="correctionValue.correctionId" value="A id">
<input type="submit" value="Delete" class="button">
</form>

But when I submit the form I get:

javax.servlet.ServletException: BeanUtils.populate

What is the way to do this?

Many, many thanks,

Request scoped form?
It could be that the correction property is null. Try changing your form 
to
use:

private CorrectionValue correctionValue = new CorrectionValue();

so that you have the sub-bean ready for beanutils to populate (it doesnt
create it for you Im afraid - though that would be a nice enhancement 
imho)

You could also instantiate it in the reset() method if you wanted
