How to get updated list values from JSP in my action?

Question

I have a JSP in which I am iterating over a list and creating an editable table.

You need the Country object is created when the params interceptor is populating your list using indexed property access.

<s:iterator value="test" id="countryList" status="stat">
  <tr>
    <td><s:textfield name="countryList[%{#stat.index}].countryCode" value="%{countryCode}" theme="simple" /></td>
    <td><s:textfield name="countryList[%{#stat.index}].countryName" value="%{countryName}" theme="simple" /></td>
  </tr>
 </s:iterator>

To let the struts populate the list you should use a type conversion annotation or equivalent in the xml configuration.

@Element(value = Country.class)
@Key(value = String.class)
@KeyProperty(value = "countryCode") 
@CreateIfNull(value = true)
private List<Country> countryList = new ArrayList<Country>;
