Greetings to you,

Do something like this (the nameToObject() macro does the trick):

- createAnObject: (const char*) argClass
{
    id mObject;

    mObject = nameToObject(argClass);

    if(!mObject)
    {
      raiseEvent(InvalidOperation,"Class %s not found\n",argClass);
    }
   mObject   = [mObject create: [self getZone]];

    return mObject;
}

Regards,
Benedikt
