Returntype List: Empty List get null on client?

[marc . baumgartner]

Hello,

I have a problem with the return type of a web service function:

public List<Customer> findCustomer(String name);

If my service returns a empty list, the list get null on the client. Is 
this a bug? Is there any workaround? Do I have to use Arrays instead of 
Lists?

Regards,
Marc
