Reference Error

Hello,

when I add the following lines to my dwr.xml

<convert match="foo.bar.SuperClass" javascript="SuperClass" converter="bean"/>
<convert match="foo.bar.SubClass" javascript="SubClass" converter="bean"/>

where SuperClass is the SuperClass of SubClass, I see the following error in my Firebug console:

"ReferenceError: SubClass is not defined"

, referencing the line in the generated js (one of the files that have creators defined)

SubClass.prototype = new SuperClass();

Please excuse my blindness, but what am I doing wrong? I am using DWR 3.0rc1.

Thanks for your help,
Florian
