> Hi,

> value="%{answer[#iterStatus.index]}" tabindex="15" autocomplete="off"/>
> </s:iterator>

> <span class="red"><strong><s:fielderror

Yeah, expression in fieldName isn't supported, please register an
issue for that.
You can use alternative syntax as specified here [1]:
<s:fielderror>
<s:param value="%{'field1'}" />
</s:fielderror>
