Here's how I'm referencing the component/template:
<s:component template="addposition.jsp">
<s:param name="name" value="'partnerPosition'"/>
</s:component>
In my addposition.jsp, I added:
<s:set name="field" value="%{parameters.name}" />
<s:property value="fieldErrors[field][0]" />
This doesn't render the error for "partnerPosition". However, if I change it
to:
<s:set name="field" value="%{parameters.name}" />
<s:property value="fieldErrors['partnerPosition'][0]" />
...it works.
In my textfield tags, parameters.name is resolved correctly, so I know I'm
passing the proper value. I just can't figure out how to pass it in as a
literal value to the fieldErrors map.
