I've never used the iterator tag like that, the standard way to use the
Struts 2 Iterator would be:

<s:iterator value="products">
  <span class="product-name"><s:property value="name <http://product.name/>
"/></span>
  <span class="product-price">&pound;<s:text name="format.currency"><s:param
value="price"/></s:text></span>
</s:iterator>

Since the iterator tag puts the current value on the top of the stack,
there's no reason to define a variable to hold it.  It's much simpler to
just use the value stack to pull the values from.  Don't know if this might
help or not.
