Hi paulsmoody
This just a sample program I know UI labels are not good, Hard coded in
Action class.
Main problem is value="<%=row.get("VALUE")%>" line not complied in JSP
page why?
<logic:iterate id="row" name="data" type="java.util.HashMap">
<html:radio property="expectedVia" value="<%=row.get("VALUE")%>"/>
</logic:iterate>

I would expect you to have a problem with the jsp. You
have an ArrayList with each element being a Map. When
you iterate over the ArrayList with the logic:iterate
tag each element, identified by "row", is a Map. This
means that the "<bean:write name="row"
property="label"/>" will fail because there is no
getLabel method for the Map.
You could try a <%=row.get("LABEL)%> to get the stored
label from the Map which should work.
However, I am not sure this is the best solution as
you are coding your UI labels in your Action which is
not best practice as far as I know.
Hope this was of help.
