Struts2: Using a variable value as property name

In my jsp, I have a label inside an iterator over a list of objects which have a "text" property:

<s:iterator value="survey.questions">
   <s:label for="d_%{id}" value="%{text}"></s:label>

   .....

<s:iterator/>

Now, since I want to localize the text inside the label, I added a property for every single language I support (textEN, textIT, etc...), and so I want the property name to be read from a local variable I previously set in the page, for example with:

<s:set var="loc" value="textEN" />

I cannot manage to do this, I tried with the following expression

<s:label for="d_%{id}" value="%{#loc}"></s:label>

But it prints nothing.

SOLVED.

I had to add an id to the iterator

<s:iterator value="survey.questions" id="question">

and then directly access the property with this syntax:

<s:label for="d_%{id}" value="%{#question[#loc]}"/>

Thank you all.

You must put the string into single quotes to stop struts from take this text as a variable name:

<s:set var="loc" value="'textEN'"/>

Now your %{#loc} should work.
