Thank you again Nathan. We have already addressed the "ugly hack", and
plugged up that potential hole. We won't be trying anything in that area.
We are installing 1.5 at this time, and will be applying your first
solution.

No, the map literal syntax is new to 1.5. however, there are ugly,
dangerous hacks like this:
#set( $object = 0 )
#set( $personnelRecord =
$object.class.forName('java.util.HashMap').newInstance() )
but i can't in good conscience recommend that. i think you should
just create a tool that returns new HashMaps on demand and put the
tool in the context.
public class MapMaker {
public Map makeMap() {
return new HashMap();
}
}
context.put("mapMaker", new MapMaker());
#set( $personnelRecord = $mapMaker.makeMap() )
#set( $foo = $mapMaker.put('name', "...") )
and so on...

Thank you Nathan.
I do not need a specific object type, but also am not using Velocity
1.5. Is there an equivalent syntax available in 1.4 to allow me to
create the map?
