Binding TextArea to a List Element in a Map

I'm creating a dynamic form and was hoping to avoid some domain specificity.

I'm wondering if it is possible to bind the first element of a List<String> that is a value in a Map to a textarea.

Example Command Object:

Code:

---

public class FormObject(){
    private Map<Integer, List<String>> formMap = new HashMap<Integer,    List<String>>();

    public FormObject

    public Map<Integer, List<String>> getformMap(){
        return this.formMap;
    }

    public void setFormMap(Map<Integer, List<String>> formMap){
          this.formMap = formMap;
    }
}

---

Example JSP (assume 'key' exists in the map with a not null list as a value):

Code:

---

    <form:form modelAttribute="formObject">
          <form:textarea path="formMap[key]" />
    </form:form>

---

I've also tried the following but I don't even know if its legal:

Code:

---

    <form:form modelAttribute="formObject">
          <form:textarea path="formMap[key][0]" />
    </form:form>

---

In the past I know I've bound a textarea to the specific elements in a list:

Code:

---

    <form:form modelAttribute="someFormObject">
          <form:textarea path="someList[0]" />
    </form:form>

---

I can bind the map value to <form:radiobuttons> and <form:checkboxes> without any issue.

Any advice would be appreciated and I am happy to clarify if this doesn't make sense.

Thanks!
