Hi
you cannot referenct bean value this way...
<html:radio property="mapProp" value='<bean:write name="mapID" property="key"/>' />
if you want to put a dynamic value there , then you have to use
jsp scriplet (or what it is) like this
<html:radio property="mapProp" value='<%= (mapID class name)mapID.getKey() %>' />
atleast i coudnt find any other way to solve these problem...
In this cases it realy is better to use som of these JSTL stuff..
