iterator and <s:radio /> question

[Jordan Smith]

hi!

I was half answered in the past and am still stuck.

i have list of qustions, and have to iterate over them. for each one to display the possible answers, and to save what the user have chose.

so i wrote:

<s:iterator value="videoQuestion" status="pos">
<s:property value="%{pos.count}" />. <s:property value="content" />
<s:radio name="answer%{id}" list="answers" listKey="id" listValue="content" />
</s:iterator>

1. how can i save what the user chose?
i tried to declare in my action class:
List<String> answer;

but it's null.

I have to know which answers where chosen.

2. <s:property value="%{pos.count}" />. is empty. i would like to display the iterator value like 1,2,3 etc.

How can i do it?

The name should use array notation; put the index inside square brackets ([]).

Try %{#pos.count}.
