Binding TextArea to a List Element in a Map

[Hurshai]

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:

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):

     <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:

     <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:

     <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!
