@ Server side , I have a list into a bean .

@ Client side , I use :

1. 
   
2. function callJava() {   
3. $.getJSON("../reference/test", { name: $('#name').val()}, function(result) {
4.                          // result is a bean that has a list 
5.           alert(result.fooList.length);
6. });
7. }

I need to be able to render this list later via FreeMarker .
What is killing me when I replaced this list with a String variable , it works fine like : 

2. function callJava() {   
3. $.getJSON("../reference/test", { name: $('#name').val()}, function(result) {
4. alert(result.stringVariable)
5.            
6. });
7. }
