Retrieve field from value stack passed through Tiles

Question

I'm using Tiles 2.0 with Struts2 and what I'm trying to do is populate an action bean from the value stack, i.e.

<s:property value="myBean.cod1"/>

would populate something like AS0000123

Now, what happens if in my tile's definition I have something like this:

<definition name="fieldPurpose1" template="fieldPurposeTemplate.jsp">
    <put-attribute name="field" value="myBean.cod1"/>
</definition>

And so, in the template I'm trying to:

<s:set name="fieldSimple"><tiles:insertAttribute name="field"/></s:set>
<s:property value="%{#fieldSimple}"/>

But what I get is the text myBean.cod1 not the populated one. Any ideas?

The thing is that in the jsp i don't know the name of the bean's field i'm trying to populate, it is parametrized through a tiles definition and the problem is than i can't use that parametrized value to retrieve the value of the bean's field. I have tried several ways, but they all fail. — josemaria_liso, Apr 04 '16 at 06:31

The value is the key, and you can use this key to find another value using OGNL index reference operator.

<s:set name="fieldSimple"><tiles:insertAttribute name="field"/></s:set>
<s:property value="%{#attr[#fieldSimple]}"/>
