No way to bind an indexed property with primitive elements.

[Lachezar]

Spring Framework 3.1.1.RELEASE.
I fail to successfully bind the contents of a list of primitive types (their wrappers actually).

Model bean:

 class Bean {
   private List<Double> elements;

   public List<Double> getElements() {
     if (elements == null)
       elements = new ArrayList<>();
     return elements;
   }
   public void setElements(List<Double> elements) {
     this.elements = elements;
   }

   public Double getElement(int pos) {
     if (elements == null || elements.size() <= pos)
       return null;
     return elements.get(pos);
   }
   public void setElement(int pos, Double element) {
     if (elements == null)
       elements = new ArrayList<>(pos+1);
     while (elements.size() < pos + 1)
       elements.add(null);
     elements.set(pos, element);
   }
 }

I tried the following configurations (FreeMarker view), but none worked:

 <@s.bind "bean.elements(0)"/>
 <@s.bind "bean.elements[0]"/>
 <@s.bind "bean.element(0)"/>
 <@s.bind "bean.element[0]"/>

I get any of the following:

 org.springframework.beans.NullValueInNestedPathException: Invalid property 'elements' of bean class [com.company.Bean]: Could not instantiate property type [java.lang.Double] to auto-grow nested property path: java.lang.InstantiationException: java.lang.Double

 org.springframework.beans.InvalidPropertyException: Invalid property 'elements[0]' of bean class [com.company.Bean]: Illegal attempt to get property 'prices' threw exception; nested exception is org.springframework.beans.NullValueInNestedPathException: Invalid property 'elements' of bean class [com.company.Bean]: Could not instantiate property type [java.lang.Double] to auto-grow nested property path: java.lang.InstantiationException: java.lang.Double

What is the proper way to bind collections of primitives in Spring Web MVC?
Any resources I can find only deal with collections of beans, which DOES NOT work for me!
