No way to bind an indexed property with primitive elements.

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

Model bean:

Code:

---

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:

Code:

---

<@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:

Code:

---

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!
