This will work. You just have to provide getter and setter for your list.
<s:iterator value="myList" status="stat">
<s:textfield name="myList[%{#stat.index}].field1" />
<s:textfield name="myList[%{#stat.index}].field2" />
</s:iterator>
public List<MyClass> getMyList()
{
return myList;
}
public void setMyList(List<MyClass>myList)
{
this.myList = myList;
}
