Struts2 - OGNL 参数化名称

Question

I have a generic jsp which is in charge of printing some values, the values depends on a parameter.

For example, I have an object car with and attribute color and a object house with the same attribute, I want to use the same jsp receiveng the name of the object as a parameter.

<jsp:include page="/jsp/prv/generic/PaintColor.jsp" >
    <jsp:param name="element" value="car" />
</jsp:include>  

So, I want to print the value of car color. I try to do it like this:

<s:set var="propertyName">${param.element}.color<s:set/>

<s:property value="%{#attr.propertyName}" />

It doesnt work, but if I do

<s:textfield name="%{#attr.propertyName}"/>

it works perfect.

How can I use the parametrized name in avalue?
