I thought you would dynamic_cast for TransferGroupHandler instead of the base 
Handler class? AFAIK there is no problem to 
dynamic_cast<TransferGroupHandler*>(someHandlerPtr)

Another solution would be to add a pure virtual method isTransferGroup() to 
the base Handler class and then implement it as "return false" in 
TransferHandler and as "return true" in TransferGroupHandler.

Cheers,
Carsten
