Spring 3 use PersistentSet to nest form:input types on jsp

[gtazok]

I have a problem. I have an entity that has many Set into, and i want to generate a jsp form that can bind these sets. The problem is:

i can't set the path of the form:input tag.

Data:

public class Implant implements java.io.Serializable {

    // Fields

    private Integer id;

    private Set analyzers = new Set(0); //with some attributes like model etc
    private Set trainings = new HashSet(0);
    //getters and setters omitted
    }

Jsp

<c:forEach items="${implant.analyzers}" varStatus="loop" var="item">
<c:choose>
<c:when test="${item.id eq 1}">
<div id="implant.analyzers${loop.index}.wrapper" class="hidden">
</c:when>
<c:otherwise>
<div id="implant.analyzers${loop.index}.wrapper">
</c:otherwise>
</c:choose>
<form:input path="implant.analyzers[${loop.index}].model" /> //HERE IS THE ERROR
<form:input path="implant.analyzers[${loop.index}].privateaddress" /> //HERE IS THE ERROR

the big problem is i cannot generate the correct path for the form:input!! i cannot get the array index because is not an array. Because the hibernate mapping, i cannot change the Set to ArrayList, or i get mappingexceptions.

So, there is a way to do this with Sets?

Thank you
