I thought it just saves the reference to the object in the hashtable. You
should have your user object eventhough it is being used through the User
interface. The UserFactory will create an instance of your object. So you
should just be able to cast it...
if ( rundata.getUser() instanceof MyUser )
{
MyUser mu = (MyUser)rundata.getUser();
/* do your stuff */
}
else
{
/* error code? */
}
Or you could just attempt the cast and catch/not catch the exception...
