Hibernate Command Object with Set Field

I am using a Hibernate code generated bean as a command object in my Spring MVC web application. The command has a field which is of type java.util.Set which needs to be represented in the form. This seems difficult, however, because a Set cannot be represented as an indexed property since it is not indexable (doesn't implement java.util.List). I do not want to convert this field to a List because in Hibernate this would require an additional index column on the child table even though we don't care about ordering.

Is there a way to represent a java.util.Set field in a form?

Thanks

If you're using JSTL, you can use

Code:

---

<c&#58;forEach var='item' items='$&#123;mySet&#125;' varStatus='status'>
<option id="<c&#58;out value='$&#123;status.index&#125;'/>" value="<c&#58;out value='$&#123;item.id&#125;'/>"><c&#58;out value='$&#123;item.value&#125;'/></option>
</c&#58;forEach>

Of course the same effect can be reached by simply using Java scriptlets like with mySet.iterator().
