Nested properties using

[Simon MARTIN]

Hi,
I'm using an array of SchuelerMatura-Objects in a DynaValidatorForm, being 
defined like this in struts-config:

<form-bean name="fachklForm" type="org.apache.struts.validator.DynaValidatorForm">
            <form-property name="schuelerMatura" 
type="org.mmo.model.SchuelerMatura[]"/>
        </form-bean>

I want to show and edit those elements in a table, whereas I iterate through the 
array as follows:

<c:forEach var="schuelerMatura" items="${fachklForm.map.schuelerMatura}" 
varStatus="status">
<tr>
    <td><c:out value="${schuelerMatura.schueler.vorname}" /> <c:out 
value="${schuelerMatura.schueler.nachname}" /> </td>
	<c:forEach var="schuelerMatura.fachklausuren" 
items="${schuelerMatura.fachklausuren}" varStatus="loopStatus">
		<td><html:text indexed="true" name="schuelerMatura.fachklausuren" 
property="note"/></td>
	</c:forEach>
	<td><html:checkbox indexed="true" name="schuelerMatura" property="toChange"/></td>
</tr>

This works quite fine for schueler.*name and toChange. Fachklausuren is a Set in 
my SchuelerMatura-class, so I simply iterate through this Set again. (The Action 
makes sure that there are always three elements in it). Showing the values works 
fine, but when I change one of the fields from 'fachklausuren', the Action 
doesn't realize it, respectively the values of the elements have not changed.

I think that this is the problem (here's a sample row, showing the plain text of 
my page):
<tr>
    <td>Max Mustermann </td>
	
		<td><input type="text" name="schuelerMatura.fachklausuren[0].note" value=""></td>
	
		<td><input type="text" name="schuelerMatura.fachklausuren[1].note" value="2"></td>
	
		<td><input type="text" name="schuelerMatura.fachklausuren[2].note" value=""></td>
	
	<td><input type="checkbox" name="schuelerMatura[0].toChange" value="on"></td>
</tr>

As you can see, the index is not included in the schuelerMatura-part of the 
fachklausuren-fields, so I assume it can't be mapped back after being submitted.

It's the same with
	<c:forEach var="fachklausuren" items="${schuelerMatura.fachklausuren}" 
varStatus="loopStatus">

I'd thought about something like
	<c:forEach var="schuelerMatura[${status.index}].fachklausuren" 
items="${schuelerMatura.fachklausuren}" varStatus="loopStatus">

for the inner forEach, which gives an exception.
Anybody can give me a hint on how to handle that?
Thanks in advance.
Kind regards,
  Simon
